In the Linux kernel, the following vulnerability has been resolved:
swiotlb: fix out-of-bounds TLB allocations with CONFIG_SWIOTLB_DYNAMIC
Limit the free list length to the size of the IO TLB. Transient pool can be
smaller than IO_TLB_SEGSIZE, but the free list is initialized with the
assumption that the total number of slots is a multiple of IO_TLB_SEGSIZE.
As a result, swiotlb_area_find_slots() may allocate slots past the end of a
transient IO TLB buffer.
