An update that solves 7 vulnerabilities and has 9 fixes is now available.
Description:
The SUSE Linux Enterprise 15 SP2 LTSS kernel was updated receive various
security and bugfixes.
The following security bugs were fixed:
o CVE-2022-0435: Fixed remote stack overflow in net/tipc module that validate
domain record count on input (bsc#1195254).
o CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c
(bnc#1193867).
o CVE-2022-22942: Fixed stale file descriptors on failed usercopy (bsc#
1195065).
o 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).
o 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).
o 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).
o CVE-2022-0330: Fixed flush TLBs before releasing backing store (bsc#
1194880).
The following non-security bugs were fixed:
o bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds()
(bsc#1194227).
o btrfs: tree-checker: Add EXTENT_ITEM and METADATA_ITEM check (bsc#1195009).
o btrfs: tree-checker: annotate all error branches as unlikely (bsc#1195009).
o btrfs: tree-checker: check for BTRFS_BLOCK_FLAG_FULL_BACKREF being set
improperly (bsc#1195009).
o hv_netvsc: Set needed_headroom according to VF (bsc#1193506).
o net, xdp: Introduce xdp_init_buff utility routine (bsc#1193506).
o net, xdp: Introduce xdp_prepare_buff utility routine (bsc#1193506).
o net: allow retransmitting a TCP packet if original is still in queue (bsc#
1188605 bsc#1187428).
o net: mana: Add RX fencing (bsc#1193506).
o net: mana: Add XDP support (bsc#1193506).
o net: sch_generic: aviod concurrent reset and enqueue op for lockless qdisc
(bsc#1183405).
o net: sched: add barrier to ensure correct ordering for lockless qdisc (bsc#
1183405).
o net: sched: avoid unnecessary seqcount operation for lockless qdisc (bsc#
1183405).
o net: sched: fix packet stuck problem for lockless qdisc (bsc#1183405).
o net: sched: fix tx action reschedule issue with stopped queue (bsc#
1183405).
o net: sched: fix tx action rescheduling issue during deactivation (bsc#
1183405).
o net: sched: replaced invalid qdisc tree flush helper in qdisc_replace (bsc#
1183405).
o net_sched: avoid resetting active qdisc for multiple times (bsc#1183405).
o net_sched: get rid of unnecessary dev_qdisc_reset() (bsc#1183405).
o net_sched: use qdisc_reset() in qdisc_destroy() (bsc#1183405).
o nvme: add 'iopolicy' module parameter (bsc#1177599 bsc#1193096).
o xfrm: fix MTU regression (bsc#1185377, bsc#1194048).
