Affected: AlmaLinux:8: bpftrace

BPFtrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). BPFtrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. The BPFtrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap

Security Fix(es):

* bpftrace: unprivileged users can force loading of compromised linux headers (CVE-2024-2313)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

If kernel headers need to be extracted, bpftrace will attempt to load them from a temporary directory. An unprivileged attacker could use this to force bcc to load compromised linux headers. Linux distributions which provide kernel headers by default are not affected by default.
