Description OSIDB Bzimport 2026-05-28 11:04:54 UTC 
In the Linux kernel, the following vulnerability has been resolved:

spi: mpc52xx: fix use-after-free on registration failure

Make sure to disable and free the interrupts in case controller
registration fails to avoid a potential use-after-free and resource
leak.

This issue was flagged by Sashiko when reviewing a controller
deregistration fix.
