advisory.\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of ttys could lead to a use-after-free. (CVE-2020-36557)\n\n - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer dereference and general protection fault. (CVE-2020-36558)\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 - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. 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:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root.

therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-083 advisory.\n\n - A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system. (CVE-2022-0500)\n\n - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.\n This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition. (CVE-2022-1158)\n\n - A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled.\n This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. (CVE-2022-1263)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently. (CVE-2022-29582)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag.

The mixed IPID assignment method with the\n hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session\n or terminate that session. (CVE-2020-36516)\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 memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the\n small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of\n service problem. (CVE-2022-1012)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel\n (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input\n validation. This could lead to local escalation of privilege with System execution privileges needed. User\n interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the\n machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector\n (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation\n (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow\n an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to\n cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14\n and later versions. (CVE-2022-29581)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where\n virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-\n free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race\n condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale\n TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak. (CVE-2022-1280)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.\n The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend.

referenced in the SUSE-SU-2022:3450-1 advisory.\n\n - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set. (CVE-2016-3695)\n\n - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). (CVE-2020-27784)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\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 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 memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with System execution privileges needed.

(CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

(CVE-2021-33061)\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 - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)\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 - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.\n (CVE-2022-0812)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. (CVE-2022-1419)\n\n - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)\n\n - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel (CVE-2022-20132)\n\n - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege when opening and closing inet sockets with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)\n\n - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition.

User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream kernel (CVE-2022-20154)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. 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:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. (CVE-2022-32296)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250.
