The _xfs_buf_find function in fs/xfs/xfs_buf.c in the Linux kernel before 3.7.6 does not validate block numbers, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the ability to mount an XFS filesystem containing a metadata inode with an invalid extent map.

Security readout for executives and security teams

CVE-2013-1819 is a Linux kernel XFS filesystem bug that can let a local user crash a system by mounting a malformed XFS filesystem. The business impact is service interruption on affected legacy systems, not confirmed remote compromise. Exposure is most plausible on older Linux kernels before 3.7.6 with XFS support, especially where local users can mount filesystem images or removable media. The bundle does not identify modern affected distribution package ranges beyond linked vendor advisories. Address during normal vulnerability remediation for legacy Linux systems, escalating if shared users can mount untrusted media. The main confirmed risk is outage from a local crash, so internet-facing emergency treatment is not supported by the provided evidence. Mitigation focus: Apply fixed Linux kernel updates from the relevant distribution vendor.; Upgrade kernels older than 3.7.6 where vendor backports are unavailable.; Restrict untrusted local users from mounting XFS filesystems or disk images..
