Description OSIDB Bzimport 2024-09-04 20:22:53 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Input: MT - limit max slots

syzbot is reporting too large allocation at input_mt_init_slots(), for
num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).

Since nobody knows possible max slots, this patch chose 1024.
