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.</p> <p>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.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>iommu/amd: Do not reallocate GA log buffers on resume</p> <p>Commit c5e1a1eb9279 (&#34;iommu/amd: Simplify and Consolidate Virtual APIC (AVIC) Enablement&#34;) moved the GA log allocation from iommu_init_pci() to enable_iommus_vapic(), which is called on every resume.</p> <p>iommu_init_ga_log() assigns iommu-&gt;ga_log and iommu-&gt;ga_log_tail unconditionally.
