CVE-2026-102729

What is CVE-2026-102729?

The gx_binres_theme_load() function in Eclipse ThreadX Guix encounters a critical flaw by allocating a theme buffer incorrectly, allowing for the possibility of a buffer overflow. When a non-existent theme ID is requested, the function attempts to access a null or zero-byte buffer, which can potentially lead to undefined behavior. This vulnerability could allow attackers to manipulate memory, potentially leading to arbitrary code execution or other detrimental impacts on system integrity.
