CVE-2026-46322
A flaw was found in the Linux kernel's tun driver. This vulnerability occurs when the buildskb function fails within tunxdpone, leading to a failure to free an allocated memory page. Each such failure results in a memory leak, where a 'page-frag chunk' is not released. Over time, repeated...

CVE-2026-46322
The CVE pertains to the Linux kernel tun driver (tun_xdp_one) where a page allocated for a frame by vhost_net_build_xdp() is not freed when build_skb() fails, causing a memory leak. Specifically, if build_skb() fails, ret is set to -ENOMEM and the code jumps to the error path without freeing the ...

In the Linux kernel, the following vulnerability has been resolved: tap: free page on error paths in tap get user xdp tap get user xdp rejects a frame shorter than ETH HLEN with -EINVAL, and returns -ENOMEM when build skb fails. Both paths jump to the err label without freeing the page that vhost...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip4ip6err Oskar Kjos reported the following problem. ip4ip6err calls icmpsend on a cloned skb whose cb was written by the IPv6 receive path as struct inet6skbparm. icmpsend passes IPCBskb2 to...
kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...
