Description

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4035-1 advisory.

The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2023-39194: Fixed an out of bounds read in the XFRM subsystem (bsc#1215861).
- CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem (bsc#1215860).
- CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858).
- CVE-2023-42754: Fixed a NULL pointer dereference in the IPv4 stack that could lead to denial of service (bsc#1215467).
- CVE-2023-4389: Fixed a reference counting issue in the Btrfs filesystem that could be exploited in order to leak internal kernel information or crash the system (bsc#1214351).
- CVE-2023-5345: fixed an use-after-free vulnerability in the fs/smb/client component which could be exploited to achieve local privilege escalation. (bsc#1215899)
- CVE-2023-42753: Fixed an array indexing vulnerability in the netfilter subsystem. This issue may have allowed a local user to crash the system or potentially escalate their privileges (bsc#1215150).
- CVE-2023-1206: Fixed a hash collision flaw in the IPv6 connection lookup table. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95% (bsc#1212703).
- CVE-2023-4921: Fixed a use-after-free vulnerability in the QFQ network scheduler which could be exploited to achieve local privilege escalatio (bsc#1215275).
- CVE-2023-4622: Fixed a use-after-free vulnerability in the Unix domain sockets component which could be exploited to achieve local privilege escalation (bsc#1215117).
- CVE-2023-4623: Fixed a use-after-free issue in the HFSC network scheduler which could be exploited to achieve local privilege escalation (bsc#1215115).
- CVE-2023-4155: Fixed a flaw in KVM AMD Secure Encrypted Virtualization (SEV). An attacker can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages. (bsc#1214022)
