Description
A flaw was found in the Linux kernel's Marvell NFC (Near Field Communication) driver. During firmware download operations, the driver removes packet headers and reads command data before verifying that the received packet length is valid. An attacker could exploit this vulnerability by submitting a truncated frame, triggering an out-of-bounds memory read. This issue primarily results in a system crash and Denial of Service (DoS).
