Name of the Vulnerable Software and Affected Versions Ubuntu Linux version 6.8 Ubuntu Linux version 6.17 Ubuntu Linux version 7.0

Description AppArmor SAUCE patches incorrectly validate the size of an internal structure, which leads to an out-of-bounds read in notification handling code. An unprivileged local user can trigger this issue, potentially resulting in information disclosure from adjacent slab objects (memory caches used for allocating objects of a certain size).
