CVE-2024-35814

Memory corruption or hang via misaligned slot allocation

Published May 17, 2024 · Updated Aug 5, 2026

Memory corruption in the Linux kernel allows local users to corrupt memory or hang a virtual machine through SWIOTLB allocation. The swiotlb_find_slots search can return a page-unaligned span after a prior allocation leaves area->index unaligned, while swiotlb_alloc converts it to a struct page and double-allocates the first 2 KiB slot. Reachability requires virtio-vsock in a virtual machine using a restricted DMA SWIOTLB pool; the bounded consequences are buffer corruption and a hang.
