A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.35% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: linux (Debian:12) 5.16.10-1; dtb-aarch64 (openSUSE:Leap 15.5) 5.14.21-150500.55.80.1; kernel-64kb (openSUSE:Leap 15.5) 5.14.21-150500.55.80.2.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to linux (Debian:12) 5.16.10-1; dtb-aarch64 (openSUSE:Leap 15.5) 5.14.21-150500.55.80.1; kernel-64kb (openSUSE:Leap 15.5) 5.14.21-150500.55.80.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system.
