CVE-2013-1819

UnknownEPSS 0.44%

Last modified

CVE-2013-1819 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
