Summary
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.
