CVE-2022-2347
HIGH7.1

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.

CVE-2022-30767
CRITICAL9.8

nfs_lookup_reply in net/nfs.c in Das U-Boot through 2022.04 (and through 2022.07-rc2) has an unbounded memcpy with a failed length check, leading to a buffer overflow. NOTE: this issue exists because of an incorrect fix for CVE-2019-14196.

CVE-2022-33967
HIGH7.8

squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.
