Vulnerability from github – Published: 2025-08-16 12:30 – Updated: 2025-11-18 18:32

Details

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

wifi: mt76: mt7925: Fix null-ptr-deref in mt7925_thermal_init()

devm_kasprintf() returns NULL on error. Currently, mt7925_thermal_init() does not check for this case, which results in a NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.

Severity ?

5.5 (Medium)
