CVE-2026-80682

CVE-2026-80682 is a Linux kernel RISC-V memory-management flaw in the vmemmap_start_pfn computation during early boot (sparse_init in mm/sparse.c ). A unit mismatch was introduced when MAX_FOLIO_VMEMMAP_ALIGN—measured in bytes of struct page storage—was fed directly into VMEMMAP_ADDR_ALIGN, which...

EUVD-2026-67558

In the Linux kernel, the following vulnerability has been resolved: riscv/mm: use physical alignment for vmemmapstartpfn RISC-V computes vmemmapstartpfn by rounding physrambase down to VMEMMAPADDRALIGN. That alignment must therefore be expressed in the physical-address domain. Commit 476849b0fba4...
