Vulnerability from fkie_nvd - Published: 2008-05-12 21:20 - Updated: 2026-06-16 22:53
Severity
Summary
The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW and UTIME_OMIT combinations are used, which allows local users to modify file times of arbitrary files, possibly leading to a denial of service.
