CVE-2026-98555

A flaw was found in the Linux kernel's Logical Link Control (LLC) subsystem. When an error occurs during network packet header initialization, the kernel mistakenly frees the incorrect memory buffer, resulting in a use-after-free condition, a double-free, and memory leaks. An attacker could exploit this flaw to crash the system, resulting in a Denial of Service (DoS), or potentially execute arbitrary code.
