Vulnerability in Linux Kernel Affecting Packet Processing

CVE-2026-43030

What is CVE-2026-43030?

A vulnerability in the Linux kernel's bpf subsystem allows for improper validation of packet pointers. When the conditions of 'regsafe()' are met, it may incorrectly indicate that a valid packet range is present, leading to potential manipulation of state and exploitation within the packet processing framework. This may affect the integrity and security of applications relying on accurate network data handling.
