Description

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.
A flaw was found in the Linux kernel's NFC subsystem, where the write() call allows a mismatch between data length and count values. For example, a call with a data length of 3 bytes but a count of 15 could lead to inconsistencies in processing NFC packets.
