CVE-2024-35941

REJECTED CVE A use-after-free vulnerability was identified in the Linux kernel's net subsystem, specifically in skbuff handling. The issue arises from an overflow of the skb-networkheader a u16 value, causing skbnetworkoffsetskb to return a negative value. This results in the skbpull function...

CVE-2024-35941

This CVE (CVE-2024-35941) has concrete details in connected sources: a use-after-free in the Linux kernel net subsystem, due to skb->network_header overflow (u16) that makes skb_network_offset(skb) return a negative value. Consequently, __skb_pull() can move skb->data to memory outside skb-...
