CVE-2024-46707 Open this link in a new tabHow to fix?
There is no fixed version for Centos:8 kernel-zfcpdump-modules-extra.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-extra package and not the kernel-zfcpdump-modules-extra package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Make ICC_SGI_EL1 undef in the absence of a vGICv3
On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_SGI_EL1 registers is trapped to EL2.
We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?).
The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.
