EUVD-2026-39204

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and setup UUID-size byte before...

CVE-2026-53253

The CVE-2026-53253 entry concerns the Linux kernel Bluetooth BNEP path. A short BNEP SDU could be processed without validating required bytes in bnep_rx_frame and bnep_rx_control, leading to a potential access of unverified data (KASAN). The fix adds proper length validation by using skb_pull_dat...

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,...
