SUSE-SLE-Module-RT-15-SP2-2022-289

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 nsim_bpf_map_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/tee_shm.c in the TEE subsystem in the Linux kernel that occured because of a race condition in tee_shm_get_from_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 legacy_parse_param which could have led to a local privilege escalation (bsc#1194517). - CVE-2022-0322: Fixed a denial of service in SCTP sctp_addto_chunk (bsc#1194985). The following non-security bugs were fixed: - ext4: Avoid trim error on fs with small groups (bsc#1191271). - fget: clarify and improve __fget_files() 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 crash_kexec_post_notifiers option (bsc#1193901). - tpm: fix potential NULL pointer access in tpm_del_char_device (bsc#1184209, bsc#1193660). - vfs: check fd has read access in kernel_read_file_from_fd() (bsc#1194888).
