Answer in brief
CVE-2023-52453 records a High severity (CVSS 7.1) vulnerability in hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume When the optional PRE_COPY support was added to speed up the device compatibility check, it failed to update the saving/resuming data pointers based on the fd offset. This results in migration data corruption and when the device gets started on the destination the following error is reported in some cases, [ 478.907684] arm-smmu-v3 arm-smmu-v3.2.auto: event 0x10 received: [ 478.913691] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000310200000010 [ 478.919603] arm-smmu-v3 arm-smmu-v3.2.auto: 0x000002088000007f [ 478.925515] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.931425] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.947552] hisi_zip 0000:31:00.0: qm_axi_rresp [error status=0x1] found [ 478.955930] hisi_zip 0000:31:00.0: qm_db_timeout [error status=0x400] found [ 478.955944] hisi_zip 0000:31:00.0: qm sq doorbell timeout in function 2
