In the Linux kernel, the following vulnerability has been resolved: media: anysee: fix null-ptr-deref in anyseemasterxfer In anyseemasterxfer, msg is controlled by user. When msgi.buf is null and msgi.len is zero, former checks on msgi.buf would be passed. Malicious data finally reach...

CVE-2023-54093

The CVE-2023-54093 issue affects the Linux kernel in the media/anysee driver. Root cause: in anysee_master_xfer, user-controlled msg i entries could lead to a null pointer dereference when msg[i].buf is null and msg[i].len is zero; a length check prevents the crash. The patch adds a guard on msg[...
