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.
