CVE-2022-49790

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: iforce - invert valid length check when fetching device IDs<br /> <br /> syzbot is reporting uninitialized value at iforce_init_device() [1], for<br /> commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer<br /> when fetching device IDs") is checking that valid length is shorter than<br /> bytes to read. Since iforce_get_id_packet() stores valid length when<br /> returning 0, the caller needs to check that valid length is longer than or<br /> equals to bytes to read.
