Overview
CVE-2026-98583 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
nfc: nfcmrvl: validate helper command length before pull
The firmware download receive path removes the NCI data header and
reads the helper command before validating the remaining packet length.
A short frame can therefore reach the data access before the malformed
packet is rejected.
Validate the complete helper command length before stripping the NCI
data header.
