Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: Input: iforce - invert valid length check when fetching device IDs syzbot is reporting uninitialized value at iforce_init_device() [1], for commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer when fetching device IDs") is checking that valid length is shorter than bytes to read. Since iforce_get_id_packet() stores valid length when returning 0, the caller needs to check that valid length is longer than or equals to bytes to read.
