high Tenable Cloud Security Plugin ID 461014

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: Fix accepting
 multiple L2CAP_ECRED_CONN_REQ Currently the code attempts to accept requests regardless of the command
 identifier which may cause multiple requests to be marked as pending (FLAG_DEFER_SETUP) which can cause
 more than L2CAP_ECRED_MAX_CID(5) to be allocated in l2cap_ecred_rsp_defer causing an overflow. The spec is
 quite clear that the same identifier shall not be used on subsequent requests: 'Within each signaling
 channel a different Identifier shall be used for each successive request or indication.'

 control-and-adaptation-protocol-specification.html#UUID-32a25a06-4aa4-c6c7-77c5-dcfe3682355d So this
 attempts to check if there are any channels pending with the same identifier and rejects if any are found.
 (CVE-2026-23395)
