Title
wifi: mt76: fix out-of-bounds access in mmio copy helpers
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix out-of-bounds access in mmio copy helpers mt76_mmio_write_copy() and mt76_mmio_read_copy() iterate up to ALIGN(len, 4), so a length that is not a multiple of four reads past the source buffer (write_copy) or writes past the destination (read_copy). Copy the aligned body in the loop and handle the remaining tail through a 4-byte bounce buffer, keeping the register access width unchanged.
Severity
