as referenced in the ELSA-2022-1988 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. 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 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.

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\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 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 - 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 - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in\n the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could\n 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\n SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a\n 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\n (CVE-2021-3759)\n\n - A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint\n 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\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 - An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to\n crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S\n 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\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 - In uvc_scan_chain_forward of uvc_driver.c, there is a possible linked list corruption due to an unusual\n root cause. This could lead to local escalation of privilege in the kernel with no additional execution\n privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android\n 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\n overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community\n 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\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.

the ALSA-2022:1988 advisory.\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 - 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 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 - 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 - 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 - 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 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 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 - 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 - 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 - 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 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 - 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 - LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.\n (CVE-2021-26401)\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 - 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 - 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-2021-42739)\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 - 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 - 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 - 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 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 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.

User interaction is\n not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-154177719References:\n Upstream kernel (CVE-2021-0941)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions\n before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the\n system or possibly escalate their privileges on the system. The highest threat from this vulnerability is\n to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\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\n crash or a leak of internal kernel information. The highest threat from this vulnerability is to system\n availability. (CVE-2021-3743)\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 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 - A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint\n information for further use in traditional network attacks. (CVE-2021-3773)\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 - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in\n the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could\n potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)\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 read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and\n SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a\n user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\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 - 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 - LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.\n (CVE-2021-26401)\n\n - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,\n allowing them to execute arbitrary code within the kernel context. This affects\n arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)\n\n - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev\n without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.\n (CVE-2021-37159)\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. (CVE-2021-42739)\n\n - An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to\n crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S\n implementation bug in the handling of the SRR1 register values. (CVE-2021-43056)\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 - 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 - 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 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 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.

the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does not check the nla_nest_start_noflag return value. (CVE-2019-16089)\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 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 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.

vulnerabilities as referenced in the SUSE-SU-2022:0289-1 advisory.\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 denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was found in the way users call some interrupts with high frequency from one of the guests.A local user could use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711) (CVE-2021-4135)\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 - kernel: fs_context: heap overflow in legacy parameter handling (CVE-2022-0185)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {"exploitabilityScore": 2.5, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.4, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-02-03T00:00:00", "type": "nessus", "title": "SUSE SLES15 Security Update : kernel (SUSE-SU-2022:0289-1)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-28711", "CVE-2021-4083", "CVE-2021-4135", "CVE-2021-4149", "CVE-2021-4197", "CVE-2021-4202", "CVE-2021-44733", "CVE-2021-45485", "CVE-2021-45486", "CVE-2022-0185", "CVE-2022-0322"], "modified": "2023-01-16T00:00:00", "cpe": ["p-cpe:/a:novell:suse_linux:cluster-md-kmp-rt", "p-cpe:/a:novell:suse_linux:dlm-kmp-rt", "p-cpe:/a:novell:suse_linux:gfs2-kmp-rt", "p-cpe:/a:novell:suse_linux:kernel-devel-rt", "p-cpe:/a:novell:suse_linux:kernel-rt", "p-cpe:/a:novell:suse_linux:kernel-rt-devel", "p-cpe:/a:novell:suse_linux:kernel-rt_debug", "p-cpe:/a:novell:suse_linux:kernel-rt_debug-devel", "p
