{"id":"RLSA-2022:7444","summary":"Moderate: kernel-rt security and bug fix update","details":"The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es):\n\n* off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516)\n\n* Race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558)\n\n* use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640)\n\n* Memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002)\n\n* smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168)\n\n* NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617)\n\n* swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854)\n\n* Uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016)\n\n* Race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048)\n\n* use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055)\n\n* use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184)\n\n* NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)\n\n* buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078)\n\n* nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)\n\n* openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)\n\n* use-after-free when psi trigger is destroyed while being polled (CVE-2022-2938)\n\n* net/packet: slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)\n\n* possible to use the debugger to write zero into a location of choice (CVE-2022-21499)\n\n* Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)\n\n* Memory leak in drivers/hid/hid-elo.c (CVE-2022-27950)\n\n* Double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)\n\n* Use after free in SUNRPC subsystem (CVE-2022-28893)\n\n* use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)\n\n* DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c (CVE-2022-36946)\n\n* nfs_atomic_open() returns uninitialized data instead of ENOTDIR (CVE-2022-24448)\n\nFor more details about the security issue(s), including the impact, a CVSS score,
