CVE-2026-43224 is fixed in 23 products on 1 platform, first by ALAS2023-2026-1702, released May 11, 2026. It is not reported as exploited. Patch Radar priority: Routine.
In the Linux kernel, the following vulnerability has been resolved: io_uring/zcrx: fix sgtable leak on mapping failures In an unlikely case when io_populate_area_dma() fails, which could only happen on a PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA machine, io_zcrx_map_area() will have an initialised and not freed table. It was supposed to be cleaned up in the error path, but !is_mapped prevents that.
