CVE-2026-24450: An integer overflow vulnerability exists in the uncompressed_fp_dng_load_raw functionality of LibRaw Commit 8dc68e2.

CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 0.59% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: LibRaw (AlmaLinux:9) 0.21.1-2.el9_7, 0.21.1-2.el9_8; LibRaw-devel (AlmaLinux:9) 0.21.1-2.el9_7, 0.21.1-2.el9_8; libraw (Alpine:v3.24) 0.22.2-r0.

Low priority for now. Upgrade to LibRaw (AlmaLinux:9) 0.21.1-2.el9_7, 0.21.1-2.el9_8; LibRaw-devel (AlmaLinux:9) 0.21.1-2.el9_7, 0.21.1-2.el9_8; libraw (Alpine:v3.24) 0.22.2-r0 or later.
