Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
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.
