CVE-2026-72138

The CVE describes a Linux kernel issue in xen/gntdev where gntdev_ioctl_map_grant_ref() could leak memory if copy_to_user() failed after adding a mapping and not releasing the acquired reference. The root cause involves mismanaged error paths: on failure to copy operation results back to userspac...

In the Linux kernel, the following vulnerability has been resolved: xfrm: natkeepalive: avoid double free on send error natkeepalivesend frees the keepalive skb whenever the IPv4 or IPv6 send helper reports an error. That cleanup is only correct before the skb is handed to the output path. Once...

CVE-2026-72136 xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink

In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrminterface: require CAPNETADMIN in the device netns for changelink xfrmichangelink operates on at most two netns, devnetdev and the interface link netns xi-net.

CVE-2026-72137

CVE-2026-72137 : In the Linux kernel, the xfrm nat_keepalive path suffers a double-free of the keepalive skb on send errors. Specifically, nat_keepalive_send() frees the skb when IPv4/IPv6 send helpers report an error, but after ip_build_and_send_pkt() or ip6_xmit() takes ownership the cleanup is...

CVE-2026-72136

CVE-2026-72136 affects the Linux kernel, specifically the xfrm subsystem and the xfrm_interface changelink flow. The root cause is a netns permission check mismatch: xfrmi_changelink() can be invoked in a caller’s netns that has CAP_NET_ADMIN, while the target interface may reside in a different ...
