Vulnerability from github – Published: 2024-11-05 18:32 – Updated: 2024-11-08 21:33

Details

In the Linux kernel, the following vulnerability has been resolved:

md/raid10: fix null ptr dereference in raid10_size()

In raid10_run() if raid10_set_queue_limits() succeed, the return value is set to zero, and if following procedures failed raid10_run() will return zero while mddev->private is still NULL, causing null ptr dereference in raid10_size().

Fix the problem by only overwrite the return value if raid10_set_queue_limits() failed.

Severity

5.5 (Medium)
