CVE-2026-98158

The Linux kernel contains a vulnerability in the ppp_async component where the frame-error path in process_input_packet() incorrectly resets a reused skb's headroom to zero. This violates the NET_SKB_PAD guarantee, leading to a kernel panic (filter under-panic) or an out-of-bounds read when CCP c...

CVE-2026-80612: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: lwtunnel: Drop skb metadata before LWT encapsulation skb metadata is meant for passing information between XDP and TC. It lives in the skb headroom, immediately before skb-data. LWT programs cannot access the skbuff-datameta...
