CVE-2024-41021

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the handling of VM FAULT HWPOISON in the do exception() function. Since there is no support for HWPOISON, MEMORY FAILURE, or ARCH HAS COPY MC on s390, VM FAULT HWPOISON is not expected in do exception(). However, due to a commit that made PTE MARKER SWAPIN ERROR more general, it is possible to see VM FAULT HWPOISON in combination with PTE MARKER POISONED. To fix this, VM FAULT HWPOISON is treated the same as VM FAULT SIGBUS, similar to x86 when MEMORY FAILURE is not configured. Unexpected fault flags are also printed for easier debugging.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
