CVE-2026-43461 is fixed in linux on 1 platform by DEBIAN-CVE-2026-43461 (version 6.19.10-1), released May 15, 2026. It is not reported as exploited. Patch Radar priority: High.
In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: Fix DMA mapping error handling Fix three bugs in aml_sfc_dma_buffer_setup() error paths: 1. Unnecessary goto: When the first DMA mapping (sfc->daddr) fails, nothing needs cleanup. Use direct return instead of goto. 2. Double-unmap bug: When info DMA mapping failed, the code would unmap sfc->daddr inline, then fall through to out_map_data which would unmap it again, causing a double-unmap. 3. Wrong unmap size: The out_map_info label used datalen instead of infolen when unmapping sfc->iaddr, which could lead to incorrect DMA sync behavior.
