In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fix silent overflow for phys vec to sgt In case MMIO size is bigger than 4G and peer2peer DMA goes through host bridge, we trigger a code path that assigns the total linked IOVA which is greater than 4G to mappedlen...

CVE-2026-98242

A vulnerability in the Linux kernel dma-buf subsystem allows for a silent overflow when the MMIO size exceeds 4G during peer-to-peer DMA through a host bridge. The root cause is that mapped_len was declared as a 32-bit unsigned int, causing a wrap-around when accumulating size_t lengths. This tru...
