5.5 · MEDIUMOverview
CVE-2023-53362 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 17, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: don't assume child devices are all fsl-mc devices
Changes in VFIO caused a pseudo-device to be created as child of
fsl-mc devices causing a crash [1] when trying to bind a fsl-mc
device to VFIO. Fix this by checking the device type when enumerating
fsl-mc child devices.
