Linux Distros Unpatched Vulnerability : CVE-2024-38667

high Nessus Plugin ID 228593

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: riscv: prevent pt_regs corruption for secondary idle threads Top of the kernel thread stack should be reserved for pt_regs. However this is not the case for the idle threads of the secondary boot harts. Their stacks overlap with their pt_regs, so both may get corrupted. Similar issue has been fixed for the primary hart, see c7cdd96eca28 (riscv:
prevent stack corruption by reserving task_pt_regs(p) early). However that fix was not propagated to the secondary harts. The problem has been noticed in some CPU hotplug tests with V enabled. The function smp_callin stored several registers on stack, corrupting top of pt_regs structure including status field.
As a result, kernel attempted to save or restore inexistent V context. (CVE-2024-38667)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
