CVE-2026-53253 Bluetooth: bnep: reject short frames before parsing

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-2026-53072

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix locking in hciconnrequestevt with HCIPROTODEFER When protocol sets HCIPROTODEFER, hciconnrequestevt calls hciconnectcfmconn without hdev-lock. Generally hciconnectcfm assumes it is held, and if conn is deleted...

CVE-2026-53072

The CVE-2026-53072 vulnerability affects the Linux kernel Bluetooth subsystem, specifically hci_conn_request_evt() when HCI_PROTO_DEFER is active. The issue arises because hci_connect_cfm(conn) is called without holding hdev->lock, breaking the expected lock discipline and allowing a Use-After...

kernel: nvmet-tcp: fix race between ICReq handling and queue teardown

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...
