A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is a tracking bug for the kernel part of the mitigation. Upstream kernel patch: <a href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1be7107fbe18eed3e319a6c3e83c78254b693acb">https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1be7107fbe18eed3e319a6c3e83c78254b693acb</a>
