CVE-2025-50897 Details

A vulnerability in the RISC-V BOOM SonicBOOM 1.2 processor implementation has been identified, where valid virtual-to-physical address translations with write permissions in SV39 mode incorrectly trigger a Store/AMO access fault during store instructions. This issue arises despite proper page table entries and valid memory access modes. The fault occurs when transitioning into virtual memory and attempting store operations in mapped kernel memory, suggesting a flaw in the memory management unit, physical memory protection, or memory access enforcement logic. The vulnerability may lead to unexpected kernel panics or denial-of-service conditions in affected systems.
