Input validation error in Linux kernel - CVE-2025-38710

Vulnerability identifier: #VU114846

CSH Severity: Low

CVSS v4: 6.8 [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]

CVE-ID: CVE-2025-38710

CWE-ID: CWE-20

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to improper input validation within the gfs2_dinode_in() function in fs/gfs2/glops.c, within the dir_make_exhash() function in fs/gfs2/dir.c. A local user can perform a denial of service (DoS) attack.
