CVE-2026-43461
Description
A flaw was found in the Linux kernel, specifically within the spi: amlogic: spifc-a4 module. This vulnerability involves errors in the handling of Direct Memory Access (DMA) mapping within the aml_sfc_dma_buffer_setup() function. These errors include a double-unmap bug and an incorrect unmap size, which can lead to improper memory synchronization. An attacker could potentially exploit these memory management issues to cause a system crash, leading to a Denial of Service (DoS).
