In the Linux kernel, the following vulnerability has been resolved: staging: nvec: fix use-after-free in nvec_rx_completed() In nvec_rx_completed(), when an incomplete RX transfer is detected, nvec_msg_free() is called to return the message back to the pool by clearing its 'used' atomic flag. Immediately after this, the code accesses nvec->rx->data[0] to check the message type. Since nvec_msg_free() marks the pool slot as available via atomic_set(), any concurrent or subsequent call to nvec_msg_alloc() could claim that same slot and overwrite its data[] array. Reading nvec->rx->data[0] after freeing the message is therefore a use-after-free. Fix this by saving the message type byte before calling nvec_msg_free(), then using the saved value for the battery quirk check.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142480 advisory.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8876-1 advisory.

    It was discovered that the i.MX clock driver in the Linux kernel did not properly handle certain memory     allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could     possibly use this to cause a denial of service (system crash). (CVE-2022-3114)

Tenable has extracted the preceding description block directly from the Ubuntu 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 remote Ubuntu 24.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8781-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

Tenable has extracted the preceding description block directly from the Ubuntu 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.

  - staging: nvec: fix use-after-free in nvec_rx_completed() In nvec_rx_completed(), when an incomplete RX     transfer is detected, nvec_msg_free() is called to return the message back to the pool by clearing its     'used' atomic flag. Immediately after this, the code accesses nvec->rx->data[0] to check the message type.
    Since nvec_msg_free() marks the pool slot as available via atomic_set(), any concurrent or subsequent call     to nvec_msg_alloc() could claim that same slot and overwrite its data[] array. Reading nvec->rx->data[0]     after freeing the message is therefore a use-after-free. Fix this by saving the message type byte before     calling nvec_msg_free(), then using the saved value for the battery quirk check. (CVE-2026-72489)

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

An update of the linux package has been released.
