Descriptions
In the Linux kernel, the following vulnerability has been resolved: af_packet: fix vlan_get_tci() vs MSG_PEEK Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found
by syzbot. Rework vlan_get_tci() to not touch skb at all,
so that it can be used from many cpus on the same skb. Add a const qualifier to skb argument. [1]

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: af_packet: arreglo vlan_get_tci() vs MSG_PEEK La confirmación culpada olvidó el caso MSG_PEEK, lo que permitió un bloqueo [1] como lo encontró syzbot. Reelabore vlan_get_tci() para que no toque skb en absoluto, de modo que pueda usarse desde muchas CPU en el mismo skb. Agregue un calificador const al argumento skb.
