CVE-2010-1641

Publication date 1 June 2010

Last updated 24 July 2024

Ubuntu priority

The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel before 2.6.34-git10 does not verify the ownership of a file, which allows local users to bypass intended access restrictions via a SETFLAGS ioctl request.
