Description
Security update for the Linux Kernel The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. Transient execution side-channel attacks attacking the Branch History Buffer (BHB), named 'Branch Target Injection' and 'Intra-Mode Branch History Injection' are now mitigated. The following security bugs were fixed: - CVE-2022-0001: Fixed Branch History Injection vulnerability (bsc#1191580). - CVE-2022-0002: Fixed Intra-Mode Branch Target Injection vulnerability (bsc#1191580). - CVE-2022-0847: Fixed a vulnerability were a local attackers could overwrite data in arbitrary (read-only) files (bsc#1196584). - CVE-2022-0617: Fixed a null pointer dereference in UDF file system functionality. A local user could crash the system by triggering udf_file_write_iter() via a malicious UDF image. (bsc#1196079) - CVE-2022-0644: Fixed a denial of service by a local user. A assertion failure could be triggered in kernel_read_file_from_fd() (bsc#1196155). - CVE-2021-44879: In gc_data_segment() in fs/f2fs/gc.c, special files were not considered, which lead to a move_data_page NULL pointer dereference (bsc#1195987). - CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in drivers/net/hamradio/yam.c (bsc#1195897). - CVE-2022-0487: A use-after-free vulnerability was found in rtsx_usb_ms_drv_remove() in drivers/memstick/host/rtsx_usb_ms.c (bsc#1194516). - CVE-2022-0492: Fixed a privilege escalation related to cgroups v1 release_agent feature, which allowed bypassing namespace isolation unexpectedly (bsc#1195543). - CVE-2022-24448: Fixed an issue in fs/nfs/dir.c. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should have occured, but the server instead returned uninitialized data in the file descriptor (bsc#1195612). - CVE-2022-25375: The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory (bsc#1196235). - CVE-2022-0516: Fixed missing check in ioctl related to KVM in s390 allows kernel memory read/write (bsc#1195516). - CVE-2022-25258: The USB Gadget subsystem lacked certain validation of interface OS descriptor requests, which could have lead to memory corruption (bsc#1196096). - CVE-2022-24958: drivers/usb/gadget/legacy/inode.c mishandled dev->buf release (bsc#1195905). The following non-security bugs were fixed: - btrfs: check for missing device in btrfs_trim_fs (bsc#1195701). - gve: Add RX context (jsc#SLE-23652). - gve: Add a jumbo-frame device option (jsc#SLE-23652). - gve: Add consumed counts to ethtool stats (jsc#SLE-23652). - gve: Add optional metadata descriptor type GVE_TXD_MTD (jsc#SLE-23652). - gve: Correct order of processing device options (jsc#SLE-23652). - gve: Fix GFP flags when allocing pages (jsc#SLE-23652). - gve: Implement packet continuation for RX (jsc#SLE-23652). - gve: Implement suspend/resume/shutdown (jsc#SLE-23652). - gve: Move the irq db indexes out of the ntfy block struct (jsc#SLE-23652). - gve: Recording rx queue before sending to napi (jsc#SLE-23652). - gve: Update gve_free_queue_page_list signature (jsc#SLE-23652). - gve: Use kvcalloc() instead of kvzalloc() (jsc#SLE-23652). - gve: fix for null pointer dereference (jsc#SLE-23652). - gve: fix the wrong AdminQ buffer queue index check (jsc#SLE-23652). - gve: fix unmatched u64_stats_update_end() (jsc#SLE-23652). - gve: remove memory barrier around seqno (jsc#SLE-23652). - lib/iov_iter: initialize 'flags' in new pipe_buffer (bsc#1196584). - net: tipc: validate domain record count on input (bsc#1195254). - nfsd: allow delegation state ids to be revoked and then freed (bsc#1192483). - nfsd: allow lock state ids to be revoked and then freed (bsc#1192483). - nfsd: allow open state ids to be revoked and then freed (bsc#1192483). - nfsd: do not admin-revoke NSv4.0 state ids (bsc#1192483). - nfsd: prepare for supporting admin-revocation of state (bsc#1192483). - powerpc/pseries/ddw: Revert 'Extend upper limit for huge DMA window for persistent memory' (bsc#1195995 ltc#196394). - scsi: lpfc: Fix pt2pt NVMe PRLI reject LOGO loop (bsc#1189126). - scsi: target: iscsi: Fix cmd abort fabric stop race (bsc#1195286).
