high Tenable Cloud Security Plugin ID 470834

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Inject SEA if
kvm_translate_vncr() can't resolve PFN kvm_handle_vncr_abort() assumes that s1_walk_result conveys an
abort when kvm_translate_vncr() returns -EFAULT. This is not always the case as it's possible to encounter
'late' failures on the output of S1 translation, e.g. a GFN outside of the memslots. Fix it by preparing
an external abort before returning from kvm_translate_vncr(). Get rid of the BUG_ON() in the fault
injection path while at it. (CVE-2026-80665)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.21 or later.
