CVE-2026-45254

Linux Kernel

Description

In the case of the cap_net service, when a key present in the old limit was omitted from the new limit, the missing key was treated as -allow any- instead of being rejected. In certain scenarios, an application that had previously restricted a subset of network operations could ask for a new limit that extended the permissions of the process.
