CVE-2024-49941: Linux Kernel
Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved: gpiolib: Fix potential NULL pointer dereference in gpiod_get_label() In `gpiod_get_label()`, it is possible that `srcu_dereference_check()` may return a NULL pointer, leading to a scenario where `label->str` is accessed without verifying if `label` itself is NULL. This patch adds a proper NULL check for `label` before accessing `label->str`. The check for `label->str != NULL` is removed because `label->str` can never be NULL if `label` is not NULL. This fixes the issue where the label name was being printed as `(efault)` when dumping the sysfs GPIO file when `label == NULL`.
Affected products
- Linux Linux Kernel: from 6.9, before 6.11.3 (fixed in 6.11.3); version 6.12 only
