CWE-787  (opens in a new tab)

How to fix?

There is no fixed version for Debian:11 u-boot.

NVD Description

Note: Versions mentioned in the description apply only to the upstream u-boot package and not the u-boot package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a wLength greater than 4096 bytes, they can write beyond the heap-allocated request buffer.
