CVSS v3.1

Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.43
Description
The issue is related to the handling of shared interrupts in the Linux kernel's drm/lima component. When the driver is removed, the clocks are disabled early, but the interrupts remain registered until the end of the removal process. This can cause a crash if the driver is removed in a kernel with CONFIG DEBUG SHIRQ enabled. The problem arises because the interrupt handlers access device registers, which assume that the clocks are enabled.
Recommendations
To resolve the issue, update the Linux kernel to version 6.6.43 or later. As a temporary workaround, consider disabling the removal of the drm/lima driver in kernels with CONFIG DEBUG SHIRQ enabled until a patch is available.
