CVE-2026-80688

In the Linux kernel, the following vulnerability has been resolved: riscv: drop init from veccheckunalignedaccessspeedallcpus This function runs within a kthread and need not necessarily finish before system finishes boot and freeinitmem unmaps the .init.text section. This function makes calls to...

CVE-2026-80682

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...

CVE-2026-80688

CVE-2026-80688 affects the Linux kernel on the RISC-V architecture. The vulnerable component is the function vec_check_unaligned_access_speed_all_cpus, which carries an __init annotation but executes within a kthread . If the SBI calls it makes are slow (e.g., due to debug output), the kthread ma...

CVE-2026-80682

CVE-2026-80682 is a unit mismatch bug in the Linux kernel 's RISC-V memory management subsystem (riscv/mm). When computing vmemmap_start_pfn, the kernel fed MAX_FOLIO_VMEMMAP_ALIGN (measured in bytes of struct page storage) directly into VMEMMAP_ADDR_ALIGN, which operates in the physical-address ...

CVE-2026-80523

A flaw was found in the Linux kernel. The HDMA Hardware Direct Memory Access clock, responsible for the internal TCM Tightly Coupled Memory access path of the X100 RISC-V core, was not set as critical. This oversight allows the clock to be shut off, which can lead to a system hang, for example,...

CVE-2026-74751

A flaw was found in the Linux kernel's RISC-V Reduced Instruction Set Computer - V ZBB-optimized strnlen function. This vulnerability occurs because the strnlen loop attempts to read one word beyond the intended boundary. If the read operation crosses an unmapped memory page, it can lead to a...
