CVE intelligence and bounded remediation

CVE-2023-53073 — Linux Linux Kernel security vulnerability

Medium CVSS 5.5

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/core: Always clear status for idx The variable 'status' (which contains the unhandled overflow bits) is not being properly masked in some cases, displaying the following warning: WARNING: CPU: 156 PID: 475601 at arch/x86/events/amd/core.c:972 amd_pmu_v2_handle_irq+0x216/0x270 This seems to be happening because the loop is being continued before the status bit being unset, in case x86_perf_event_set_period() returns 0. This is also causing an inconsistency because the "handled" counter is incremented, but the status bit is not cleaned. Move the bit cleaning together above, together when the "handled" counter is incremented.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
