CVE-2024-46745

In the Linux kernel, the following vulnerability has been resolved:

Input: uinput - reject requests with unreasonable number of slots

When exercising uinput interface syzkaller may try setting up device

with a really large number of slots, which causes memory allocation

failure in input_mt_init_slots(). While this allocation failure is

handled properly and request is rejected, it results in syzkaller

reports. Additionally, such request may put undue burden on the

system which will try to free a lot of memory for a bogus request.

Fix it by limiting allowed number of slots to 100. This can easily

be extended if we see devices that can track more than 100 contacts.
