CVE-2026-43224

The CVE-2026-43224 entry concerns the Linux kernel io_uring/zcrx subsystem. A memory leak could occur when mapping fails in io_populate_area_dma() on PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA, as io_zcrx_map_area() would allocate a sgtable that isn’t freed due to the error path not freeing it when !is_...

CVE-2026-43223

CVE-2026-43223 concerns the Linux kernel media driver pvrusb2. The issue arises when pvr2_send_request_ex() submits a write URB and, if the subsequent read URB submission fails (e.g., due to -ENOMEM), returns early without waiting for the write to complete. Because the same URB structure is reuse...
