[$] Per-call-site slab caches for heap-spraying protection

Thursday August 22, 2024. 04:15 PM , from LWN.net
One tactic often used by attackers set on compromising a system is heap spraying; in
short, the attacker fills as much of the heap as possible with crafted data
in the hope of getting the target system to use that data in a bad way. If
heap spraying can be blocked, attackers will lose an important tool. The
kernel has some heap-spraying defenses now, including the dedicated bucket allocator merged for the
upcoming 6.11 release, but its author, Kees Cook, thinks that more can be
done.
