Security update for the Linux Kernel (Live Patch 23 for SLE 15 SP3)

This update for the Linux Kernel 5.3.18-150300_59_90 fixes several issues.

The following security issues were fixed:

  • CVE-2023-32233: Fixed a use-after-free in Netfilter nf_tables when processing batch requests (bsc#1211187).
  • CVE-2023-2156: Fixed a flaw in the networking subsystem within the handling of the RPL protocol (bsc#1211395).
  • CVE-2023-3567: Fixed a use-after-free in vcs_read in drivers/tty/vt/vc_screen.c (bsc#1213244).
  • CVE-2023-35001: Fixed an out-of-bounds memory access flaw in nft_byteorder that could allow a local attacker to escalate their privilege (bsc#1213063).
  • CVE-2023-1077: Fixed a type confusion in pick_next_rt_entity(), that could cause memory corruption (bsc#1208839).
  • CVE-2023-2176: Fixed an out-of-boundary read in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA (bsc#1210630).
  • CVE-2023-3090: Fixed a heap out-of-bounds write in the ipvlan network driver (bsc#1212849).

Описание

In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.

Описание

A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system.

Описание

A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege.

Описание

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.

Описание

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.

Описание

A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information.
