CVE-2026-53002

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of `sprintf` and insufficient buffer sizing in the `mangle_content_len()` function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue to cause a denial of service or other unspecified impacts.
