Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

CVE-2021-4083: Fixed race condition in Unix domain socket garbage collection that could lead to read memory after free (bsc#1193727).
CVE-2021-4135: Fixed an information leak in the nsimbpfmap_alloc function (bsc#1193927).
CVE-2021-4149: Fixed improper lock operation in btrfs that allowed users to crash the kernel or deadlock the system (bsc#1194001).
CVE-2021-4197: Fixed a cgroup issue where lower privileged processes could write to fds of lower privileged ones that could lead to privilege escalation (bsc#1194302).
CVE-2021-4202: Fixed race condition in nci_request() that could cause use-after-free (bsc#1194529).
CVE-2021-44733: Fixed a use-after-free exists in drivers/tee/teeshm.c in the TEE subsystem in the Linux kernel that occured because of a race condition in teeshmgetfrom_id during an attempt to free a shared memory object (bnc#1193767).
CVE-2021-45485: Fixed an information leak because of certain use of a hash table which use IPv6 source addresses (bsc#1194094).
CVE-2021-45486: Fixed an information leak because the hash table is very small in net/ipv4/route.c (bnc#1194087).
CVE-2022-0185: Incorrect param length parsing in legacyparseparam which could have led to a local privilege escalation (bsc#1194517).
CVE-2022-0322: Fixed a denial of service in SCTP sctpaddtochunk (bsc#1194985).

The following non-security bugs were fixed:

ext4: Avoid trim error on fs with small groups (bsc#1191271).
fget: clarify and improve _fgetfiles() implementation (bsc#1193727).
kabi/severities: Add a kabi exception for drivers/tee/tee
kprobes: Limit max data_size of the kretprobe instances (bsc#1193669).
livepatch: Avoid CPU hogging with cond_resched (bsc#1071995).
media: Revert 'media: uvcvideo: Set unique vdev name based in type' (bsc#1193255).
moxart: fix potential use-after-free on remove path (bsc#1194516).
powerpc/fadump: Fix inaccurate CPU state info in vmcore generated with panic (bsc#1193901).
powerpc: handle kdump appropriately with crashkexecpost_notifiers option (bsc#1193901).
tpm: fix potential NULL pointer access in tpmdelchar_device (bsc#1184209, bsc#1193660).
vfs: check fd has read access in kernelreadfilefromfd() (bsc#1194888).
