Description OSIDB Bzimport 2025-08-16 12:02:00 UTC 
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.
