Missing Release of Resource after Effective Lifetime in Linux kernel - CVE-2026-90283

Vulnerability identifier: #VU151194

CSH Severity: Low

CVSS v4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90283

CWE-ID: CWE-772

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause huge page reservations to remain charged.

The vulnerability exists due to improper resource cleanup in the hugetlbfs_fill_super() failure path when initiating a hugetlbfs mount with size or min_size options and root dentry creation fails. A local user can trigger the mount failure path to cause huge page reservations to remain charged.
