Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Integer overflow

EUVDB-ID: #VU88102

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-23307

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow in raid5_cache_count() function. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel (Live Patch 9 for SLE 15 SP5) to the latest version.
