Security update for the Linux Kernel
The SUSE Linux Enterprise 15 SP3 RT kernel was updated to receive various security bugfixes. The following security bugs were fixed: - CVE-2024-1086: Fixed a use-after-free vulnerability inside the nf_tables component that could have been exploited to achieve local privilege escalation (bsc#1219434). - CVE-2023-51780: Fixed a use-after-free in do_vcc_ioctl in net/atm/ioctl.c, because of a vcc_recvmsg race condition (bsc#1218730). - CVE-2023-46838: Fixed an issue with Xen netback processing of zero-length transmit fragment (bsc#1218836). - CVE-2021-33631: Fixed an integer overflow in ext4_write_inline_data_end() (bsc#1219412). - CVE-2023-6535: Fixed a NULL pointer dereference in nvmet_tcp_execute_request (bsc#1217988). - CVE-2023-6536: Fixed a NULL pointer dereference in __nvmet_req_complete (bsc#1217989). - CVE-2023-6356: Fixed a NULL pointer dereference in nvmet_tcp_build_pdu_iovec (bsc#1217987). - CVE-2023-47233: Fixed a use-after-free in the device unplugging (disconnect the USB by hotplug) code inside the brcm80211 component (bsc#1216702). - CVE-2023-51043: Fixed use-after-free during a race condition between a nonblocking atomic commit and a driver unload in drivers/gpu/drm/drm_atomic.c (bsc#1219120). - CVE-2024-0775: Fixed use-after-free in __ext4_remount in fs/ext4/super.c that could allow a local user to cause an information leak problem while freeing the old quota file names before a potential failure (bsc#1219053). - CVE-2024-0565: Fixed an out-of-bounds memory read flaw in receive_encrypted_standard in fs/smb/client/smb2ops.c (bsc#1218832). - CVE-2023-6915: Fixed a NULL pointer dereference problem in ida_free in lib/idr.c (bsc#1218804). - CVE-2023-6040: Fixed an out-of-bounds access vulnerability while creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function (bsc#1218752). - CVE-2023-51782: Fixed use-after-free in rose_ioctl in net/rose/af_rose.c because of a rose_accept race condition (bsc#1218757). The following non-security bugs were fixed: - Store the old kernel changelog entries in kernel-docs package (bsc#1218713). - x86/entry/ia32: Ensure s32 is sign extended to s64 (bsc#1193285).
