What is CVE-2025-50897?
CVE-2025-50897 is a medium-severity denial of service vulnerability in n/a, published on 19 Aug 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A vulnerability exists in riscv-boom SonicBOOM 1.2 (BOOMv1.2) processor implementation, where valid virtual-to-physical address translations configured with write permissions (PTE_W) in SV39 mode may incorrectly trigger a Store/AMO access fault during store instructions (sd). This occurs despite the presence of proper page table entries and valid memory access modes. The fault is reproducible when transitioning into virtual memory and attempting store operations in mapped kernel memory, indicating a potential flaw in the MMU, PMP, or memory access enforcement logic. This may cause unexpected kernel panics or denial of service in systems using BOOMv1.2.
Which versions are affected by CVE-2025-50897?
It affects 1 product.
Products include Boom-Core Boomv.
How do I fix CVE-2025-50897?
