Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU84096

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-6176

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel API for the cryptographic algorithm scatterwalk functionality in scatterwalk_copychunks(). A local user can send a malicious packet with specific socket configuration and crash the OS kernel.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP3) to the latest version.
