CVE-2026-53253

CVE-2026-53253 affects the Linux kernel Bluetooth BNEP stack. The vulnerability arises when a BNEP peer sends a short SDU and the kernel bnep_rx_frame() reads the packet type, then bnep_rx_control() dereferences the control opcode or setup UUID-size byte before ensuring those bytes are present. T...

CVE-2026-46321

A flaw was found in the Linux kernel. A local attacker with access to the tun/tap device can exploit this vulnerability. By sending network frames shorter than the expected header length, the system fails to free allocated memory pages, leading to memory leaks. This can exhaust system memory,...
