- Summary
- CVE-2024-44931 affecting package kernel for versions less than 5.15.176.3-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gpio: prevent potential speculation leaks in gpio_device_get_desc()
Userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do that by calling gpio_ioctl() with an offset out of range. Offset is copied from user and then used as an array index to get the gpio descriptor without sanitization in gpio_device_get_desc().
This change ensures that the offset is sanitized by using array_index_nospec() to mitigate any possibility of speculative information leaks.
This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
