Upgrade torvalds/linux to version 6.6.160, 6.12.114, 6.18.14, 6.19.4 or higher.
Overview
Affected versions of this package are vulnerable to Arbitrary Code Execution in the BPF_PROG_DETACH process for tcx or netkit devices when no program file descriptor is provided. An attacker can bypass permission checks and remove attached BPF programs by invoking the relevant syscall as an unprivileged local user, potentially exposing network traffic, subverting policy enforcement, and disrupting network connectivity.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
