CVE-2026-45932

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix tcx/netkit detach permissions when prog fd isn't given This commit fixes a security issue where BPF_PROG_DETACH on tcx or netkit devices could be executed by any user when no program fd was provided, bypassing permission checks. The fix adds a capability check for CAP_NET_ADMIN or CAP_SYS_ADMIN in this case.
