ALSA-2022:7444 — Moderate: kernel-rt security and bug fix update

Affected: AlmaLinux:8: kernel-rt, AlmaLinux:8: kernel-rt-core, AlmaLinux:8: kernel-rt-debug, AlmaLinux:8: kernel-rt-debug-core, AlmaLinux:8: kernel-rt-debug-devel, AlmaLinux:8: kernel-rt-debug-kvm, AlmaLinux:8: kernel-rt-debug-modules, AlmaLinux:8: kernel-rt-debug-modules-extra, AlmaLinux:8: kernel-rt-devel, AlmaLinux:8: kernel-rt-kvm and 2 more

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516) * Race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558) * use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640) * Memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002) * smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168) * NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617) * swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854) * Uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016) * Race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048) * use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055) * use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184) * NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852) * buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078) * nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586) * openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-202…

A denial of service (DOS) issue was found in the Linux kernel’s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
