Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.16.3
Description
The Linux kernel contains a use-after-free flaw within the simplefb driver, specifically in the
simplefb detach genpds() function. This issue arises because the pm domain cleanup is not properly managed as devres, leading to access of an invalid pointer after the device is removed. The flaw was triggered during aperture removal on M2 Mac mini systems running the asahi kernel with Debian's kernel configuration, consistently causing a kernel crash starting with version 6.16.3. The issue involves a double free of memory associated with the framebuffer device.Recommendations
Update to a version of the Linux kernel newer than 6.16.3.
