Published: 2024-05-20 | Last Modified: 2026-05-12 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: riscv: Fix TASK_SIZE on 64-bit NOMMU On NOMMU, userspace memory can come from anywhere in physical RAM. The current definition of TASK_SIZE is wrong if any RAM exists above 4G, causing spurious failures in the userspace access routines.
