GNU elfutils eu-readelf libdw_alloc.c __libdw_thread_tail memory corruption
Noroxi assessment
Priority: Monitor (action score 9/100)
- 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: 0.66% (FIRST EPSS); higher than 50.7% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. Special conditions such as timing or configuration are required.
- Fixed version: azl3 elfutils 0.189-5 on Azure Linux 3.0 0.189-5.
Low priority for now. Upgrade to azl3 elfutils 0.189-5 on Azure Linux 3.0 0.189-5 or later.
