CVE-2026-81893: Gdk-pixbuf: gdk-pixbuf: invalid write in jpeg icc profile parser on error recovery

MediumCVSS 4.7 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: azl3 gdk-pixbuf2 2.42.10-5 on Azure Linux 3.0 2.42.10-6; azl3 gdk-pixbuf2 2.42.10-6 on Azure Linux 3.0 2.42.10-6.

Low priority for now. Upgrade to azl3 gdk-pixbuf2 2.42.10-5 on Azure Linux 3.0 2.42.10-6; azl3 gdk-pixbuf2 2.42.10-6 on Azure Linux 3.0 2.42.10-6 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image. Affected version >= 2.26.4
