In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: fix use-after-free in driver_override_show() The driver_override_show() function reads the driver_override string without holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and frees the string while holding the device_lock. This can result in a concurrent use-after-free if the string is freed by the store function while being read by the show function. Fix this by holding the device_lock around the read operation.

    In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: fix use-after-free in     driver_override_show() The driver_override_show() function reads the driver_override string without     holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and     frees the string while holding the device_lock. This can result in a concurrent use-after-free if the     string is freed by the store function while being read by the show function. Fix this by holding the     device_lock around the read operation. (CVE-2026-23221)

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

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

An update of the linux package has been released.

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

  - bus: fsl-mc: fix use-after-free in driver_override_show() The driver_override_show() function reads the     driver_override string without holding the device_lock. However, driver_override_store() uses     driver_set_override(), which modifies and frees the string while holding the device_lock. This can result     in a concurrent use-after-free if the string is freed by the store function while being read by the show     function. Fix this by holding the device_lock around the read operation. (CVE-2026-23221)

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