kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace. (CVE-2021-46283)\n\n - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS).

This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace. (CVE-2021-46283)\n\n - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS).

- A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc.

versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the ability to run PV backends in regular unprivileged guests, typically referred to as 'driver domains'.\n Running PV backends in driver domains has one primary security advantage: if a driver domain gets compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)\n\n - In gre_handle_offloads of ip_gre.c, there is a possible page fault due to an invalid memory access.

User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-210292376References: Upstream kernel (CVE-2021-39685)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - In __f2fs_setxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds memory access when an inode has an invalid last xattr entry. (CVE-2021-45469)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access.

There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. (CVE-2020-28097)\n\n - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)\n\n - In gadget_dev_desc_UDC_show of configfs.c, there is a possible disclosure of kernel heap memory due to a race condition. This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-160822094References: Upstream kernel (CVE-2021-39648)\n\n - In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-194696049References: Upstream kernel (CVE-2021-39657)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.\n (CVE-2021-45095)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-0330)\n\n - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.\n This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. (CVE-2022-0435)\n\n - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup.

Grant mapping operations\n often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success\n or failure of each one is reported to the backend driver, and the backend driver then loops over the\n results, performing follow-up actions based on the success or failure of each operation. Unfortunately,\n when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively\n implying their success from the success of related batch elements. In other cases, errors resulting from\n one batch element lead to further batch elements not being inspected, and hence successful ones to not be\n possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are\n vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and\n drivers/xen/gntdev.c.

This flaw could even allow a local attacker with special user privilege to a kernel information leak threat. (CVE-2020-27825)\n\n - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.\n Running PV backends in driver domains has one primary security advantage: if a driver domain gets compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing.

A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4.

(CVE-2021-4135)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem.

(CVE-2021-43975)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS).

However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing.

In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-0330)\n\n - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.\n This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

There are some measures taken for avoiding to pile up too much data, but those can\n be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming\n new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in\n its RX queue ring page and the next package would require more than one free slot, which may be the case\n when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)\n\n - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow\n an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)\n\n - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in\n the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the\n system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)\n\n - In gadget_dev_desc_UDC_show of configfs.c, there is a possible disclosure of kernel heap memory due to a\n race condition. This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-160822094References: Upstream kernel (CVE-2021-39648)\n\n - In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing\n bounds check. This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-194696049References: Upstream kernel (CVE-2021-39657)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some\n regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the\n memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an\n improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of\n service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces\n subsystem was found in the way users have access to some less privileged process that are controlled by\n cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of\n control groups. A local user could use this flaw to crash the system or escalate their privileges on the\n system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in\n the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem\n while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in\n drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a\n crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows\n an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory\n object. (CVE-2021-44733)\n\n - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.\n (CVE-2021-45095)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak\n because the hash table is very small. (CVE-2021-45486)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network\n protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more\n buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the\n way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or\n escalate their privileges on the system. (CVE-2022-0330)\n\n - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends\n a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.\n This flaw allows a remote user to crash the system or possibly escalate their privileges if they have\n access to the TIPC network. (CVE-2022-0435)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

(CVE-2020-27820)\n\n - An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped.\n However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out.

If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory. (CVE-2022-25375)\n\n - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)\n\n - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to obtain sensitive information from heap memory via crafted frame lengths from a device.

This flaw, under certain circumstances, allows the use of the cgroups\n v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way\n user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw\n to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)\n\n - A flaw was found in the way the 'flags' member of the new pipe buffer structure was lacking proper\n initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus\n contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache\n backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)\n\n - A flaw use after free in the Linux kernel FUSE filesystem was found in the way user triggers write(). A\n local user could use this flaw to get some unauthorized access to some data from the FUSE filesystem and\n as result potentially privilege escalation too. (CVE-2022-1011)\n\n - The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.\n (CVE-2022-22942)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the\n O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a\n regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file\n descriptor. (CVE-2022-24448)\n\n - An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The\n RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive\n information from kernel memory.

This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-160822094References: Upstream kernel (CVE-2021-39648)\n\n - In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing\n bounds check. This could lead to local information disclosure with System execution privileges needed.\n User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-194696049References: Upstream kernel (CVE-2021-39657)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some\n regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the\n memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device\n driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A\n local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an\n improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of\n service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces\n subsystem was found in the way users have access to some less privileged process that are controlled by\n cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of\n control groups. A local user could use this flaw to crash the system or escalate their privileges on the\n system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in\n the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem\n while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in\n drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a\n crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows\n an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory\n object. (CVE-2021-44733)\n\n - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.\n (CVE-2021-45095)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak\n because the hash table is very small. (CVE-2021-45486)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network\n protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more\n buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the\n way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or\n escalate their privileges on the system. (CVE-2022-0330)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing.

User interaction is not\n needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-168607263References:\n Upstream kernel (CVE-2021-0935)\n\n - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to\n multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the\n ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.\n Running PV backends in driver domains has one primary security advantage: if a driver domain gets\n compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain\n could try to attack other guests via sending events at a high frequency leading to a Denial of Service in\n the guest due to trying to service interrupts for elongated amounts of time. There are three affected\n backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch\n 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record\n relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]\n Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is\n ready to process them. There are some measures taken for avoiding to pile up too much data, but those can\n be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming\n new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in\n its RX queue ring page and the next package would require more than one free slot, which may be the case\n when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)\n\n - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow\n an authenticated user to potentially enable denial of service via local access.

A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an\n improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of\n service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces\n subsystem was found in the way users have access to some less privileged process that are controlled by\n cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of\n control groups. A local user could use this flaw to crash the system or escalate their privileges on the\n system. (CVE-2021-4197)\n\n - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in\n the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem\n while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)\n\n - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in\n drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a\n crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows\n an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory\n object. (CVE-2021-44733)\n\n - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.\n (CVE-2021-45095)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak\n because the hash table is very small. (CVE-2021-45486)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network\n protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more\n buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the\n way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or\n escalate their privileges on the system.

However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing.

However, a malicious driver domain\n could try to attack other guests via sending events at a high frequency leading to a Denial of Service in\n the guest due to trying to service interrupts for elongated amounts of time. There are three affected\n backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch\n 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record\n relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]\n Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is\n ready to process them. There are some measures taken for avoiding to pile up too much data, but those can\n be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming\n new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in\n its RX queue ring page and the next package would require more than one free slot, which may be the case\n when using GSO, XDP, or software hashing.

advisory.\n\n - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)\n\n - IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could allow a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances. IBM X-Force ID: 189296.\n (CVE-2020-4788)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\n\n - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.\n (CVE-2021-37159)\n\n - An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel.\n A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-3743)\n\n - LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.\n (CVE-2021-26401)\n\n - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. (CVE-2021-20322)\n\n - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition.

(CVE-2021-3752)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - kernel: unaccounted ipc objects in Linux kernel lead to breaking memcg limits and DoS attacks (CVE-2021-3759)\n\n - A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint information for further use in traditional network attacks. (CVE-2021-3773)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values. (CVE-2021-43056)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - In uvc_scan_chain_forward of uvc_driver.c, there is a possible linked list corruption due to an unusual root cause. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-111893654References: Upstream kernel (CVE-2020-0404)\n\n - An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case. (CVE-2020-13974)\n\n - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if unbind the driver). (CVE-2020-27820)\n\n - In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-154177719References:\n Upstream kernel (CVE-2021-0941)\n\n - kernel: reading /proc/sysvipc/shm does not scale with large shared memory segment counts (CVE-2021-3669)\n\n - kernel: DoS in ccp_run_aes_gcm_cmd() function (CVE-2021-3764)\n\n - kernel: security regression for CVE-2018-13405 (CVE-2021-4037)\n\n - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - A flaw was found in the Linux kernel. A null pointer dereference in bond_ipsec_add_sa() may lead to local denial of service. (CVE-2022-0286)\n\n - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().\n This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. (CVE-2022-1011)\n\n - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).\n This vulnerability is similar with the older CVE-2019-18808. (CVE-2021-3744)\n\n - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write. (CVE-2021-41864)\n\n - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or escalate privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

(CVE-2020-13974)\n\n - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could\n happen if removing device (that is not common to remove video card physically without power-off, but same\n happens if unbind the driver). (CVE-2020-27820)\n\n - In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This\n could lead to local escalation of privilege with System execution privileges needed. User interaction is\n not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-154177719References:\n Upstream kernel (CVE-2021-0941)\n\n - kernel: reading /proc/sysvipc/shm does not scale with large shared memory segment counts (CVE-2021-3669)\n\n - kernel: DoS in ccp_run_aes_gcm_cmd() function (CVE-2021-3764)\n\n - kernel: security regression for CVE-2018-13405 (CVE-2021-4037)\n\n - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66\n and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read\n the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's\n memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222\n 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in\n the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows\n an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information\n leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based\n attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak\n because the hash table is very small. (CVE-2021-45486)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may\n allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an\n authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - A flaw was found in the Linux kernel. A null pointer dereference in bond_ipsec_add_sa() may lead to local\n denial of service. (CVE-2022-0286)\n\n - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().\n This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in\n privilege escalation. (CVE-2022-1011)\n\n - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in\n drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).\n This vulnerability is similar with the older CVE-2019-18808. (CVE-2021-3744)\n\n - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows\n unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds\n write. (CVE-2021-41864)\n\n - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user\n calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or\n escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,\n integrity, as well as system availability.

by multiple vulnerabilities as referenced in the dsa-5096 advisory.\n\n - An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.\n (CVE-2020-29374)\n\n - An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as CVE-2021-28950. (CVE-2020-36322)\n\n - A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the system while running OSP.\n (CVE-2021-20317)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. (CVE-2021-20322)\n\n - A double free bug in packet_set_ring() in net/packet/af_packet.c can be exploited by a local user through crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected versions or rebuilding past ec6af094ea28f0f2dda1a6a33b14cd57e36a9755 (CVE-2021-22600)\n\n - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.\n Running PV backends in driver domains has one primary security advantage: if a driver domain gets compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is ready to process them. There are some measures taken for avoiding to pile up too much data, but those can be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in its RX queue ring page and the next package would require more than one free slot, which may be the case when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)\n\n - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)\n\n - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.\n (CVE-2021-3640)\n\n - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).\n This vulnerability is similar with the older CVE-2019-18808. (CVE-2021-3744)\n\n - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3752)\n\n - A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat to confidentiality, integrity, and system availability. (CVE-2021-3760)\n\n - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)\n\n - arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context.\n This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture.\n (CVE-2021-38300)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write. (CVE-2021-41864)\n\n - The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.

The\n get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider\n the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.\n (CVE-2020-29374)\n\n - An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka\n CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system\n crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as\n CVE-2021-28950. (CVE-2020-36322)\n\n - A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the\n timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user\n privileges to cause a denial of service, slowing and eventually stopping the system while running OSP.\n (CVE-2021-20317)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users\n do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux\n kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an\n off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this\n vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source\n port randomization are indirectly affected as well. (CVE-2021-20322)\n\n - A double free bug in packet_set_ring() in net/packet/af_packet.c can be exploited by a local user through\n crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected\n versions or rebuilding past ec6af094ea28f0f2dda1a6a33b14cd57e36a9755 (CVE-2021-22600)\n\n - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to\n multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the\n ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.\n Running PV backends in driver domains has one primary security advantage: if a driver domain gets\n compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain\n could try to attack other guests via sending events at a high frequency leading to a Denial of Service in\n the guest due to trying to service interrupts for elongated amounts of time. There are three affected\n backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch\n 3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\n - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record\n relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]\n Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is\n ready to process them. There are some measures taken for avoiding to pile up too much data, but those can\n be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming\n new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).\n Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.\n (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in\n its RX queue ring page and the next package would require more than one free slot, which may be the case\n when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)\n\n - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur\n because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)\n\n - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the\n way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()\n together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A\n privileged local user could use this flaw to crash the system or escalate their privileges on the system.\n (CVE-2021-3640)\n\n - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in\n drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).\n This vulnerability is similar with the older CVE-2019-18808. (CVE-2021-3744)\n\n - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to\n the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the\n system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,\n integrity, as well as system availability. (CVE-2021-3752)\n\n - A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat\n to confidentiality, integrity, and system availability. (CVE-2021-3760)\n\n - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP\n association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and\n the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)\n\n - arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when\n transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context.\n This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture.\n (CVE-2021-38300)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some\n regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the\n memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition.

potentially enable denial of service via local access. (CVE-2021-33061)\n\n - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. (CVE-2021-33655)\n\n - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.\n (CVE-2021-33656)\n\n - In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-185125206References: Upstream kernel (CVE-2021-39698)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.\n Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (CVE-2021-4159)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)\n\n - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel.
