CVE-2003-0956: Linux Kernel

Low severity, CVSS 2.6. EPSS: 0.3% chance of exploitation in the next 30 days.

Multiple race conditions in the handling of O_DIRECT in Linux kernel prior to version 2.4.22 could cause stale data to be returned from the disk when handling sparse files, or cause incorrect data to be returned when a file is truncated as it is being read, which might allow local users to obtain sensitive data that was originally owned by other users, a different vulnerability than CVE-2003-0018.
