CVE-2025-40296

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> platform/x86: int3472: Fix double free of GPIO device during unregister<br /> <br /> regulator_unregister() already frees the associated GPIO device. On<br /> ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to<br /> random failures when other drivers (typically Intel THC) attempt to<br /> allocate interrupts. The root cause is that the reference count of the<br /> pinctrl_intel_platform module unexpectedly drops to zero when this<br /> driver defers its probe.<br /> <br /> This behavior can also be reproduced by unloading the module directly.<br /> <br /> Fix the issue by removing the redundant release of the GPIO device<br /> during regulator unregistration.
