CVE-2026-80723

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds write occurs during boot when the fdt scan reserved mem() function processes dynamically-placed /reserved-memory subnodes. The function saves these subnodes into a local array of size MAX RESERVED REGIONS; however, if the device tree defines more regions than this limit, the function writes past the end of the array.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
