CVE-2026-25984

An integer overflow in the PSB (PSD v2) RLE decoding path causes a heap out-of-bounds read on 32-bit builds. This can lead to information disclosure or a crash when processing crafted PSB files.

=================================================================
==3298==ERROR: AddressSanitizer: heap-buffer-overflow on address 0xf512eb00 at pc 0xf76760b5 bp 0xffc1dfb8 sp 0xffc1dfa8

    #0 0xf76760b4 in ReadPSDChannelRLE coders/psd.c:1141

A read operation accesses a memory location beyond the intended buffer boundary. Typical impact: sensitive data disclosure or crash.

CVE-2026-25984 has a CVSS score of 3.7 (Low). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.10.3); upgrading removes the vulnerable code path.

4. Is there a fix for CVE-2026-25984? Yes. CVE-2026-25984 is fixed in 14.10.3. Upgrade to this version or later.
5. Is CVE-2026-25984 exploitable, and should I be worried? Whether CVE-2026-25984 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-25984 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
