GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2010-0727 (GCVE-0-2010-0727)

Vulnerability from cvelistv5 – Published: 2010-03-16 19:00 – Updated: 2024-08-07 00:59
VLAI
Summary
The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions.
Severity
No CVSS data available.
