CVE-2026-106066: Improper Restriction of Operations within the Bounds of a Memory Buffer in Red Hat Red Hat Enterprise Linux 10
Description
A heap-based buffer overflow was found in GIMP’s raw data export plug-in. When exporting very large images, g_malloc() sizing based on overflowing width * height * bytes-per-pixel can allocate far less memory than GEGL reads or writes during export, following integer overflow

Technical Analysis
This vulnerability involves improper restriction of operations within the bounds of a memory buffer in GIMP's raw data export plug-in. Specifically, when exporting very large images, the calculation for memory allocation using g_malloc() overflows due to width * height * bytes-per-pixel exceeding the integer limit. Consequently, less memory is allocated than required, allowing GEGL to read or write beyond the allocated buffer during export, causing a heap-based buffer overflow.
Potential Impact
The vulnerability can lead to integrity and availability impacts, such as application crashes or potential code execution due to heap-based buffer overflow. The CVSS 3.1 score is 6.3 (medium severity), reflecting the need for local access with high attack complexity and user interaction.
