CVE-2026-53273

CVE-2026-53273 describes a use-after-free in the Linux kernel TEE/OP-TEE path. When a client exits before the supplicant finishes processing, freed request memory could be dereferenced, enabling a potential crash or code execution path. The root cause is a race around request lifetime between the...

CVE-2026-53227

CVE-2026-53227 affects the Linux kernel net/openvswitch path. The issue arises when allocating the reply skb after taking ovs_mutex, where an error path can leave the skb with an ERR_PTR and later free it during cleanup, leading to a possible invalid free. The fix sets the pointer to NULL after s...
