CVE-2025-68789
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ibmpex) fix use-after-free in high/low store
The ibmpex_high_low_store() function retrieves driver data using
dev_get_drvdata() and uses it without validation. This creates a race
condition where the sysfs callback can be invoked after the data
structure is freed, leading to use-after-free.
Fix by adding a NULL check after dev_get_drvdata(), and reordering
operations in the deletion path to prevent TOCTOU.
