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...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

CVE-2026-31772 Bluetooth: hci_sync: fix stack buffer overflow in hci_le_big_create_sync

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: fix stack buffer overflow in hcilebigcreatesync hcilebigcreatesync uses DEFINEFLEX to allocate a struct hcicplebigcreatesync on the stack with room for 0x11 17 BIS entries. However, conn-numbis can hold up to...

kernel: Bluetooth: hci_event: Fix UAF in hci_conn_tx_dequeue

A flaw was discovered in the Bluetooth subsystem of the Linux kernel. When processing a HCIEVNUMCOMPPKTS event, the function hciconntxdequeue did not properly hold or release the hdev device lock, which may lead to a use-after-free of the connection structure...

CVE-2025-68305 Bluetooth: hci_sock: Prevent race in socket write iter and sock bind

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisock: Prevent race in socket write iter and sock bind There is a potential race condition between sock bind and socket write iter. bind may free the same cmd via mgmtpending before write iter sends the cmd, just as...

CVE-2025-68304

The CVE-2025-68304 entries describe a Linux kernel Bluetooth subsystem use-after-free risk in hci_core: lookup of hci_conn on the RX path. The root cause is a hdev lock/lookup/unlock/use pattern in RX that can allow concurrent deletion of hci_conn* while protocol RX processing uses it, prior to/b...

CVE-2023-53828 Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Avoid use-after-free in dbg for hciaddadvmonitor KSAN reports use-after-free in hciaddadvmonitor. While adding an adv monitor, hciaddadvmonitor calls - msftaddmonitorpattern calls - msftaddmonitorsync calls -...
