In the Linux kernel, the following vulnerability has been resolved:
net: prestera: validate firmware header length
prestera_fw_hdr_parse() reads the firmware header before checking
that the firmware image contains that header.
Reject images shorter than struct prestera_fw_header before decoding the
magic and version fields.
A flaw was found in the `prestera` network driver in the Linux kernel. The `prestera_fw_hdr_parse()` function reads the firmware header before checking that the firmware image contains the entire header. This oversight could allow a local attacker to provide a specially crafted, malformed firmware image, potentially leading to a denial of service (DoS) by causing the system to crash or become unstable.
