CVE-2023-53297

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: fix "bad unlock balance" in l2cap_disconnect_rsp conn->chan_lock isn't acquired before l2cap_get_chan_by_scid, if l2cap_get_chan_by_scid returns NULL, then 'bad unlock balance' is triggered.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

• kernel: Bluetooth: L2CAP: fix "bad unlock balance" in l2cap_disconnect_rsp (CVE-2023-53297)

• kernel: efivarfs: Fix slab-out-of-bounds in efivarfs_d_compare (CVE-2025-39817)

• kernel: Bluetooth: Fix potential use-after-free when clear keys (CVE-2023-53386)
