The vulnerability of the skb_put_padto() function in the Ethernet Frame Handler driver’s kernel code (/drivers/net/ethernet/lantiq_etop.c) allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the skbputpadto function in the Ethernet Frame Handler driver’s source code at /drivers/net/ethernet/lantiqetop.c in the Linux kernel involves copying buffers without checking their size. This constitutes a classic buffer overflow attack. Exploiting this vulnerability could...
