Improper privilege management in Linux kernel - CVE-2024-36963

Vulnerability identifier: #VU93733

CSH Severity: Low

CVSS v4 BT: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-36963

CWE-ID: CWE-269

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to read and manipulate data.

The vulnerability exists due to improperly imposed permissions within the DEFINE_SPINLOCK(), tracefs_apply_options() and tracefs_d_revalidate() functions in fs/tracefs/inode.c, within the eventfs_remount() function in fs/tracefs/event_inode.c. A local user can read and manipulate data.
