Security update for the Linux Kernel (Live Patch 29 for SLE 15 SP2)
This update for the Linux Kernel 5.3.18-150200_24_126 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-1390: Fixed remote DoS vulnerability in tipc_link_xmit() (bsc#1210779).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Описание
A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw allows a local user to crash or potentially escalate their privileges on the system.

Описание
A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.

Описание
atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).
