1) Heap-based buffer overflow

EUVDB-ID: #VU104094

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-2025-0927

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the hfs_bnode_read_key() function in HFS+ filesystem implementation. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Mitigation

Update the affected package linux-gcp to the latest version.
