CVE-2023-54093
Last modified
CVE-2023-54093 is a vulnerability of currently unknown severity. 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. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
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.
