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.
