- Summary
- riscv: process: fix kernel info leakage
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
riscv: process: fix kernel info leakage
threadstruct's s[12] may contain random kernel memory content, which may be finally leaked to userspace. This is a security hole. Fix it by clearing the s[12] array in threadstruct when fork.
As for kthread case, it's better to clear the s[12] array as well.
