CVE-2025-71098

The CVE CVE-2025-71098 affects the Linux kernel’s IP6_GRE path. Syzbot crashes were caused by ip6gre_header() relying on dynamic dev->needed_headroom/dev->hard_header_len, enabling skb underflow when an skb with insufficient headroom was used (e.g., during mld_sendpack/mld_finish_output pat...

CVE-2025-71085

The CVE-2025-71085 issue is a Linux kernel vulnerability: an oops/BUG_ON occurs in skb handling within calipso_skbuff_setattr() when headroom grows beyond INT_MAX, due to an implicit cast in __skb_cow() and a delta calculation that can become negative. The root cause is an integer overflow path t...
