CVE-2026-25988

A flaw was found in ImageMagick. When processing certain images, the msl.c component fails to correctly update the stack index, causing an image to be stored in an incorrect memory location. This memory is then not properly freed, leading to memory leaks. A remote attacker could exploit this vulnerability by providing a specially crafted image, which can lead to a Denial of Service (DoS) condition.

MODERATE: A flaw in ImageMagick can lead to memory leaks when processing images. This issue arises because the MSL image stack index is not consistently refreshed, causing images to be stored in incorrect memory locations and not properly deallocated. Red Hat products utilizing ImageMagick for image manipulation may experience resource exhaustion under specific processing conditions.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To reduce the risk of memory exhaustion, it is recommended to avoid processing untrusted or maliciously crafted image files with ImageMagick. Deploying ImageMagick operations within a sandboxed environment with appropriate resource limits can further contain potential impacts from this vulnerability.
