Echo: linux: security update to 6.12.94-1

high Tenable Cloud Security Plugin ID 465453

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to
 close channels in cleanup_listen() l2cap_chan_close() removes the channel from conn->chan_l, which must be
 done under conn->lock. cleanup_listen() runs under the parent sk_lock, so acquiring conn->lock would
 invert the established conn->lock -> chan->lock -> sk_lock order. Instead of calling l2cap_chan_close()
 directly, schedule l2cap_chan_timeout with delay 0 to close the channel asynchronously. The timeout
 handler already acquires conn->lock and chan->lock in the correct order. The timer is only armed when
 chan->conn is still set: if it is already NULL, l2cap_conn_del() has already processed this channel
 (l2cap_chan_del + l2cap_sock_teardown_cb + l2cap_sock_close_cb), so there is nothing left to do. If
 l2cap_conn_del() races in after the timer is armed, __clear_chan_timer() inside l2cap_chan_del() cancels
 it; if the timer has already fired, the handler returns harmlessly because chan->conn was cleared.
 (CVE-2026-53358)

Solution

Update the linux library and its related packages to version 6.12.94-1 or later.
