CVE-2024-42130 Information

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.
