- Summary
- CVE-2026-31692 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: add missing netlinknscapable() check for peer netns
rtnlnewlink() lacks a CAPNETADMIN capability check on the peer network namespace when creating paired devices (veth, vxcan, netkit). This allows an unprivileged user with a user namespace to create interfaces in arbitrary network namespaces, including initnet.
Add a netlinknscapable() check for CAPNETADMIN in the peer namespace before allowing device creation to proceed.
