CVE-2014-7975 (GCVE-0-2014-7975)

Vulnerability from cvelistv5 – Published: 2014-10-13 10:00 – Updated: 2024-08-06 13:03
VLAI
Summary
The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call.
