When msg[i].buf\nis null and msg[i].len is zero, former checks on msg[i].buf would be\npassed. Malicious data finally reach anysee_master_xfer. If accessing\nmsg[i].buf[0] without sanity check, null ptr deref would happen.\nWe add check on msg[i].len to prevent crash.\nSimilar commit:\ncommit 0ed554fd769a\n(\"media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()\")\n[hverkuil: add spaces around +]", "A flaw was found in the Linux kernel's anysee media driver. A local user can provide specially crafted input to the anysee_master_xfer function, leading to a null pointer dereference. This can cause a system crash, resulting in a Denial of Service (DoS)." ],
