In the Linux kernel, the following vulnerability has been resolved: driver core: platform: use generic driver_override infrastructure When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally. Note that calling match() from __driver_attach() without the device lock held is intentional. [1]

An update of the linux package has been released.

    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 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

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.

  - driver core: platform: use generic driver_override infrastructure When a driver is probed through
    __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the     driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core     driver_override infrastructure taking care of proper locking internally. Note that calling match() from
    __driver_attach() without the device lock held is intentional. [1] (CVE-2026-31527)

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