Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013348)

low Nessus Plugin ID 308069

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013348 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 Bluetooth: RFCOMM: FIX possible deadlock in rfcomm_sk_state_change

 rfcomm_sk_state_change attempts to use sock_lock so it must never be called with it locked but rfcomm_sock_ioctl always attempt to lock it causing the following trace:

 ====================================================== WARNING: possible circular locking dependency detected 6.8.0-syzkaller-08951-gfe46a7dd189e #0 Not tainted
 ------------------------------------------------------ syz-executor386/5093 is trying to acquire lock:

 but task is already holding lock:
 ffff88807badfd28 (&d->lock){+.+.}-{3:3}, at: __rfcomm_dlc_close+0x226/0x6a0 net/bluetooth/rfcomm/core.c:491

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
