The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. Transient execution side-channel attacks attacking the Branch History Buffer , 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 . - CVE-2022-0002: Fixed Intra-Mode Branch Target Injection vulnerability . - 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. - CVE-2022-0644: Fixed a denial of service by a local user. A assertion failure could be triggered in kernel_read_file_from_fd . - 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 . - CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate in drivers/net/hamradio/yam.c . - CVE-2022-0487: A use-after-free vulnerability was found in rtsx_usb_ms_drv_remove in drivers/memstick/host/rtsx_usb_ms.c . - CVE-2022-0492: Fixed a privilege escalation related to cgroups v1 release_agent feature, which allowed bypassing namespace isolation unexpectedly . - 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 . The following non-security bugs were fixed: - crypto: af_alg - get_page upon reassignment to TX SGL . - hv_netvsc: fix network namespace issues with VF support . - hv_netvsc: move VF to same namespace as netvsc device . - lib/iov_iter: initialize flags in new pipe_buffer . Special Instructions and Notes: Please reboot the system after installing this update.
