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...
kernel: Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync
A flaw was found in the Linux kernel’s Bluetooth subsystem HCI. Specifically, in the function hciaclcreateconnsync and related path hcilecreateconnsync, a connection object in state BTOPEN that is still pending command submission may be freed prematurely, leading to a use-after-free condition. An...
kernel: Bluetooth: MGMT: Fix possible UAFs
A flaw was found in the Linux kernel’s Bluetooth management subsystem net/bluetooth/mgmt.c. The mgmtpending structure may be freed while still being processed, or remain on the pending command list, which allows a use-after-free or double-free scenario. An attacker with local access to the system...
