In the Linux kernel, the following vulnerability has been resolved:
nfc/nci: Add the inconsistency check between the input data length and
count
write$nci(r0, &(0x7f0000000740)=ANY=[@ANYBLOB=“610501”], 0xf)
Syzbot constructed a write() call with a data length of 3 bytes but a count
value
of 15, which passed too little data to meet the basic requirements of the
function
nci_rf_intf_activated_ntf_packet().
Therefore, increasing the comparison between data length and count value to
avoid
problems caused by inconsistent data length and count.
