Security update for the Linux Kernel
The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2022-39188: Fixed race condition in include/asm-generic/tlb.h where a device driver can free a page while it still has stale TLB entries (bnc#1203107).

- CVE-2022-3028: Fixed race condition that was found in the IP framework for transforming packets (XFRM subsystem) (bnc#1202898).
- CVE-2022-2991: Fixed an heap-based overflow in the lightnvm implemenation (bsc#1201420).
- CVE-2022-26373: Fixed non-transparent sharing of return predictor targets between contexts in some Intel Processors (bnc#1201726).
- CVE-2022-2588: Fixed use-after-free in cls_route (bsc#1202096).
- CVE-2022-21385: Fixed a flaw in net_rds_alloc_sgs() that allowed unprivileged local users to crash the machine (bnc#1202897).
- CVE-2022-20369: Fixed out of bounds write in v4l2_m2m_querybuf of v4l2-mem2mem.c (bnc#1202347).
- CVE-2022-20368: Fixed slab-out-of-bounds access in packet_recvmsg() (bsc#1202346).
- CVE-2020-36516: Fixed an issue in the mixed IPID assignment method where an attacker was able to inject data into or terminate a victim's TCP session (bnc#1196616).
- CVE-2019-3900: Fixed infinite loop the vhost_net kernel module that could result in a DoS scenario (bnc#1133374).
The following non-security bugs were fixed:
- net_sched: cls_route: Disallowed handle of 0 (bsc#1202393).
- mm, rmap: Fixed anon_vma->degree ambiguity leading to double-reuse (bsc#1203098).
- lightnvm: Removed lightnvm implemenation (bsc#1191881).

Описание
An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.

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.

In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed.

It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0.

Описание
A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.

Описание
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.

Описание
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.
