CVE-2025-70293

Name of the Vulnerable Software and Affected Versions Denx U-Boot versions prior to 2026.04

Description An integer overflow occurs in the ext4fs get bgdtable() function. The size calculation can result in an under-allocated buffer, which is subsequently used in memcpy(). This flaw may lead to arbitrary code execution, a denial of service, or other unspecified impacts.

Recommendations Update Denx U-Boot to version 2026.04 or later. As a temporary workaround, consider restricting the use of the ext4fs get bgdtable() function until the update is applied.
