Summary
Fix critical severity security issue in
target/linux/ipq40xx/files/drivers/net/ethernet/qualcomm/essedma/edma.c.Vulnerability
V-007target/linux/ipq40xx/files/drivers/net/ethernet/qualcomm/essedma/edma.c:1976Description: The EDMA Ethernet driver copies a user-supplied MAC address into kernel memory using memcpy with a copy length (netdev->addr_len) that is not validated against the actual size of the source buffer (addr->sa_data, fixed at 14 bytes in struct sockaddr). An attacker who manipulates addr_len to a value larger than ETH_ALEN (6) causes the memcpy to read beyond the sa_data boundary and write attacker-controlled data into adjacent kernel memory, potentially overwriting function pointers and achieving full kernel code execution.
