{"id":"DEBIAN-CVE-2024-57901","details":"In the Linux kernel, the following vulnerability has been resolved:  af_packet: fix vlan_get_protocol_dgram() vs MSG_PEEK  Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found by syzbot.  Rework vlan_get_protocol_dgram() 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.
