Description OSIDB Bzimport 2025-07-03 09:01:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()

devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init()
does not check for this case, which results in a NULL pointer
