In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: reject accept queue add unless BTLISTEN New sk should not be added to parent socket accept queue after last l2capsockcleanuplisten has run in l2capsockteardowncb and state set to BTCLOSED, as that can result to...
CVE-2026-90093
CVE-2026-90093 is a use-after-free bug in the Linux kernel Bluetooth L2CAP subsystem. Since commit b66774b48dd9, l2cap_chan::conn retains a reference that remains non-NULL even after the corresponding hci_conn is deleted. Accessing fields such as hci_conn::hdev in this state causes a KASAN crash ...
