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: iommu/amd: Do not reallocate GA log
 buffers on resume Commit c5e1a1eb9279 ("iommu/amd: Simplify and Consolidate Virtual APIC (AVIC)
 Enablement") moved the GA log allocation from iommu_init_pci() to enable_iommus_vapic(), which is called
 on every resume. iommu_init_ga_log() assigns iommu->ga_log and iommu->ga_log_tail unconditionally. Each
 resume therefore replaces the boot-time pointers and leaks both old allocations. The function also uses
 GFP_KERNEL from a syscore resume callback, where interrupts are disabled and the non-boot CPUs are
 offline. Return early if both buffers are already allocated. Clear the pointers in free_ga_log() so a
 partial allocation failure cannot leave ga_log dangling. (CVE-2026-98003)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
