Overview

CVE-2023-54093 is a known-severity vulnerability. It was published on December 24, 2025.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

media: anysee: fix null-ptr-deref in anysee_master_xfer

In anysee_master_xfer, msg is controlled by user. When msg[i].buf

is null and msg[i].len is zero, former checks on msg[i].buf would be

passed. Malicious data finally reach anysee_master_xfer. If accessing

msg[i].buf[0] without sanity check, null ptr deref would happen.

We add check on msg[i].len to prevent crash.
