Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-09-23 21:30

Details

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.

Severity

5.5 (Medium)
