CVE-2024-2313

Service interruption via untrusted cached kernel headers

Published Mar 10, 2024 · Updated Mar 13, 2025

Temporary-file misuse in bpftrace allows local users to interrupt service by causing BCC to load compromised Linux headers. The unpack_kheaders_tar_xz path reuses the temporary kernel-header directory when it merely exists, without verifying that root owns it. Exploitation requires low-privileged local access and header extraction; distributions that provide kernel headers are not exposed by default.
