CVE-2026-97984
A flaw was found in the Linux kernel's IPv6 networking subsystem. A local user could cause a Denial of Service DoS by exploiting an integer overflow in the User Datagram Protocol UDP length calculation. When Path MTU Discovery is enabled on a network device configured with an unusually large...
CVE-2026-63994
A flaw was found in the Linux kernel's tunnels module. This vulnerability, categorized as a Use-After-Free UAF, arises from improper handling of network header pointers during certain packet processing operations. Specifically, functions responsible for building Internet Control Message Protocol...
SUSE CVE-2026-63992
In the Linux kernel, the following vulnerability has been resolved: tunnels: do not assume transport header in iptunnelpmtudcheckicmp In some cases, iptunnelpmtudcheckicmp can be called while skb transport header is not set. This triggers an out-of-bound access, because typeofskb-transportheader0...
CVE-2026-63994
In the Linux kernel, the following vulnerability has been resolved: tunnels: load network headers after skbcow in iptunnelpmtudbuildicmpv6 Sashiko found that iptunnelpmtudbuildicmp and iptunnelpmtudbuildicmpv6 were caching iphdr and ipv6hdr before an skbcow call which can reallocate skb-head. Fix...

CVE-2026-63993 vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()
In the Linux kernel, the following vulnerability has been resolved: vxlan: do not reuse cached iphdr value after skbtunnelcheckpmtu skbtunnelcheckpmtu can change skb-head. Reusing oldiph afer skbtunnelcheckpmtu can cause an UAF. Use instead iphdrskb as done in drivers/net/bareudp.c and...
CVE-2026-63994 tunnels: load network headers after skb_cow() in iptunnel_pmtud_build_icmp[v6]()

CVE-2026-63993
CVE-2026-63993 corresponds to a Linux kernel issue in VXLAN handling: skb_tunnel_check_pmtu() may modify skb->head, causing a stale ip_hdr() reference to be reused and potentially leading to use-after-free (UAF). The advised remediation is to use ip_hdr(skb) instead of the cached value, as imp...
