CVE-2026-63970
CVE-2026-63970 — Linux kernel vulnerability in vsock/virtio where zerocopy skb handling could fail due to allocation order: uarg must be bound before filling the skb to ensure correct lifetime handling. The fix ensures the zerocopy uarg is passed into virtio_transport_alloc_skb() and bound prior ...
CVE-2026-63924 ipv6: exthdrs: refresh nh pointer after ipv6_hop_jumbo()
In the Linux kernel, the following vulnerability has been resolved: ipv6: exthdrs: refresh nh pointer after ipv6hopjumbo ipv6hopjumbo calls pskbtrimrcsum, which can change skb pointers. Let's recompute nh pointer to make sure any change won't mess things up...
CVE-2026-63924
CVE-2026-63924 is a Linux kernel issue where in ipv6_hop_jumbo(), calling pskb_trim_rcsum() can change skb pointers. The fix recomputes the neighbor header (nh) pointer to ensure it remains correct after potential skb pointer changes, mitigating pointer misalignment risks. The vulnerability is de...
CVE-2026-63922 ipv6: exthdrs: refresh nh after handling HAO option
In the Linux kernel, the following vulnerability has been resolved: ipv6: exthdrs: refresh nh after handling HAO option ip6parsetlv caches skbnetworkheaderskb in nh while walking IPv6 TLVs. ipv6desthao may call pskbexpandhead for a cloned skb, which can move the skb head and invalidate the cached...
CVE-2026-63922
Summary: CVE-2026-63922 affects the Linux kernel IPv6 ext hdr processing. The root cause is that ip6_dest_hao() can call pskb_expand_head() on a cloned skb, which may move the skb head and invalidate a cached network header pointer used while walking IPv6 TLVs. The fix refreshes the cached networ...
