What is CVE-2020-13910?

Pengutronix Barebox versions up to v2020.05.0 are susceptible to an out-of-bounds read vulnerability within the NFS module. The issue arises from the mishandling of the length field of incoming network packets in the nfs_read_reply function located in net/nfs.c. Specifically, the exploited field is used without ensuring proper bounds checks, potentially allowing the reading of unintended memory areas, which could lead to information disclosure or other malicious exploits.
