Vulnerability CVE-2024-42130
Published: 2024-07-30

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.
