Details

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 dereference.

Prevent null pointer dereference in mt7915_mmio_wed_init().
