Linux Kernel Security Vulnerabilities
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from a NAPI instance in the netdev module that does not properly handle namespaces. This could lead to cross-namespac...
CVE-2025-21659: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: netdev: prevent accessing NAPI instances from another namespace The NAPI IDs were not fully exposed to user space prior to the netlink API, so they were never namespaced. The netlink API must ensure that at the very least NAPI...
