In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2capsockcreate btsockalloc allocates the sk object and attaches it to the provided sock object. On error l2capsockalloc frees the sk object, but the dangling pointer...
kernel: bluetooth/l2cap: sync sock recv cb and release
In the Linux kernel, the following vulnerability has been resolved: bluetooth/l2cap: sync sock recv cb and release The problem occurs between the system call to close the sock and hcirxwork, where the former releases the sock and the latter accesses it without lock protection.

CVE-2022-49910
CVE-2022-49910 (Linux kernel) : A race between two Bluetooth L2CAP flows can cause a use-after-free in l2cap_rx_state_recv (kernel 5.19.8). Specifically, an SKB queued by l2cap_reassemble_sdu may be freed by bt_sock_recvmsg/sock path, while code still accesses l2cap_ctrl in the SKB CB after l2cap...

CVE-2022-49909
The connected advisories describe CVE-2022-49909 as a Linux kernel Bluetooth L2CAP use-after-free (A2MP) in l2cap_conn_del(). When l2cap_recv_frame() processes data and creates an A2MP channel that is not held, the reference counting can reach 1, and during hci_error_reset(), l2cap_chan_unlock() ...
