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

watch_queue: Fix filter limit check

In watch_queue_set_filter(), there are a couple of places where we check that the filter type value does not exceed what the type_filter bitmap can hold. One place calculates the number of bits by:

if (tf[i].type >= sizeof(wfilter->type_filter) * 8)

which is fine, but the second does:

if (tf[i].type >= sizeof(wfilter->type_filter) * BITS_PER_LONG)

which is not. This can lead to a couple of out-of-bounds writes due to a too-large type:

(1) __set_bit() on wfilter->type_filter (2) Writing more elements in wfilter->filters[] than we allocated.

Fix this by just using the proper WATCH_TYPE__NR instead, which is the number of types we actually know about.

The bug may cause an oops looking something like:
