CVE-2024-42230
CVSS v2.0
4.6
Medium
| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the powerpc/pseries architecture in the Linux kernel. Specifically, kexec on pseries disables AIL (reloc on exc), which is required for scv instruction support, before other CPUs have been shut down. This causes an interrupt at an unexpected entry location, leading to a kernel crash. The real-mode scv interrupt vector is 0x17000, and the fixed-location head code does not support this interrupt due to high address implementation issues.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
