In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync roc_abort_sync() can deadlock with roc_work(). roc_work() holds dev->mt76.mutex, while cancel_work_sync() waits for roc_work() to finish. If the caller already owns the same mutex, both sides block and no progress is possible. This deadlock can occur during station removal when mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() -> mt7921_roc_abort_sync() invokes cancel_work_sync() while roc_work() is still running and holding dev->mt76.mutex. This avoids the mutex deadlock and preserves exactly-once work ownership.

An update of the linux package has been released.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6381 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.95-1.

    We recommend that you upgrade your linux packages.

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync roc_abort_sync() can deadlock with     roc_work(). roc_work() holds dev->mt76.mutex, while cancel_work_sync() waits for roc_work() to finish. If     the caller already owns the same mutex, both sides block and no progress is possible. This deadlock can     occur during station removal when mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->     mt7921_roc_abort_sync() invokes cancel_work_sync() while roc_work() is still running and holding     dev->mt76.mutex. This avoids the mutex deadlock and preserves exactly-once work ownership.
    (CVE-2026-53101)

Note that Nessus relies on the presence of the package as reported by the vendor.
