CVE-2022-50763
Published Dec 24, 2025
Modified Apr 15, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: marvell/octeontx - prevent integer overflows The "code_length" value comes from the firmware file. If your firmware is untrusted realistically there is probably very little you can do to protect yourself. Still we try to limit the damage as much as possible. Also Smatch marks any data read from the filesystem as untrusted and prints warnings if it not capped correctly. The "code_length * 2" can overflow. The round_up(ucode_size, 16) + sizeof() expression can overflow too. Prevent these overflows.

Frequently Asked Questions
What is CVE-2022-50763? +
In the Linux kernel, the following vulnerability has been resolved:
crypto: marvell/octeontx - prevent integer overflows
The "code_length" value comes from the firmware file. If your firmware
is untrusted realistically there is probably very little you can do to
protect yourself. Still we try to limit the damage as much as possible.
Also Smatch marks any data read from the filesystem as untrusted and
prints warnings if it not capped correctly.
The "code_length * 2" can overflow. The round_up(ucode_size, 16) +
sizeof() expression can overflow too. Prevent these overflows.
How do I check if I'm vulnerable to CVE-2022-50763? +
