Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: uinput - reject requests with unreasonable number of slots<br /> <br /> <br /> When exercising uinput interface syzkaller may try setting up device<br /> with a really large number of slots, which causes memory allocation<br /> failure in input_mt_init_slots(). While this allocation failure is<br /> handled properly and request is rejected, it results in syzkaller<br /> reports. Additionally, such request may put undue burden on the<br /> system which will try to free a lot of memory for a bogus request.<br /> <br /> Fix it by limiting allowed number of slots to 100. This can easily<br /> be extended if we see devices that can track more than 100 contacts.
