RHSA-2024:9188: Low: bpftrace security update
BPFtrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x).

The BPFtrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap<br>Security Fix(es):<br><li> bpftrace: unprivileged users can force loading of compromised linux headers (CVE-2024-2313)</li> 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.<br>Additional Changes:<br>For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.5 Release Notes linked from the References section.
