Notes
Title of the patch: Security update for the Linux RT Kernel
Description of the patch: The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2022-0435: Fixed remote stack overflow in net/tipc module that validate domain record count on input (bsc#1195254). - CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c (bnc#1193867). - CVE-2022-22942: Fixed stale file descriptors on failed usercopy (bsc#1195065). - CVE-2021-22600: Fixed double free bug in packet_set_ring() in net/packet/af_packet.c that could have been exploited by a local user through crafted syscalls to escalate privileges or deny service (bnc#1195184). - CVE-2021-39657: Fixed out of bounds read due to a missing bounds check in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local information disclosure with System execution privileges needed (bnc#1193864). - CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a race condition in gadget_dev_desc_UDC_show of configfs.c. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation (bnc#1193861). - CVE-2022-0330: Fixed flush TLBs before releasing backing store (bsc#1194880). The following non-security bugs were fixed: - bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds() (bsc#1194227). - btrfs: tree-checker: Add EXTENT_ITEM and METADATA_ITEM check (bsc#1195009). - btrfs: tree-checker: annotate all error branches as unlikely (bsc#1195009). - btrfs: tree-checker: check for BTRFS_BLOCK_FLAG_FULL_BACKREF being set improperly (bsc#1195009). - hv_netvsc: Set needed_headroom according to VF (bsc#1193506). - net, xdp: Introduce xdp_init_buff utility routine (bsc#1193506). - net, xdp: Introduce xdp_prepare_buff utility routine (bsc#1193506). - net: allow retransmitting a TCP packet if original is still in queue (bsc#1188605 bsc#1187428). - net: mana: Add RX fencing (bsc#1193506). - net: mana: Add XDP support (bsc#1193506). - net: sch_generic: aviod concurrent reset and enqueue op for lockless qdisc (bsc#1183405). - net: sched: add barrier to ensure correct ordering for lockless qdisc (bsc#1183405). - net: sched: avoid unnecessary seqcount operation for lockless qdisc (bsc#1183405). - net: sched: fix packet stuck problem for lockless qdisc (bsc#1183405). - net: sched: fix tx action reschedule issue with stopped queue (bsc#1183405). - net: sched: fix tx action rescheduling issue during deactivation (bsc#1183405). - net: sched: replaced invalid qdisc tree flush helper in qdisc_replace (bsc#1183405). - net_sched: avoid resetting active qdisc for multiple times (bsc#1183405). - net_sched: get rid of unnecessary dev_qdisc_reset() (bsc#1183405). - net_sched: use qdisc_reset() in qdisc_destroy() (bsc#1183405). - nvme: add 'iopolicy' module parameter (bsc#1177599 bsc#1193096). - xfrm: fix MTU regression (bsc#1185377, bsc#1194048).
