CVE-2026-112394
Description
A flaw was found in pillow. A remote attacker could trigger an out-of-bounds read by supplying specially crafted image dimensions and input buffers to the raw image decoders. Because the decoder calculates an image row size smaller than the unpacker's actual memory footprint, the library reads past the end of the buffer. This flaw can lead to information disclosure by exposing adjacent heap memory in output pixels or cause a Denial of Service (DoS) by crashing the application.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
