Description
A flaw was found in the Linux kernel's netfilter connection tracking (ctnetlink) component. A missing helper function call in the expectation deletion path allows a local attacker to leak the least significant byte (LSB) of an expectation object's memory address to userspace. This information disclosure could potentially aid in bypassing Address Space Layout Randomization (ASLR) and facilitate further attacks.
