No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-98946/ (Markdown: https://insights.sbomify.com/CVE-2026-98946/index.md)","id":"CVE-2026-98946","markdown":"https://insights.sbomify.com/CVE-2026-98946/index.md","name":"CVE-2026-98946","record":{"aliases":["AZL-110747","BELL-CVE-2026-98946","DEBIAN-CVE-2026-98946","GHSA-2jww-55pg-7c53","UBUNTU-CVE-2026-98946"],"analysis":null,"analysis_generated_by":null,"assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vc4: Disable the V3D interrupt across runtime suspend\n\nvc4_irq_disable() masks the V3D interrupt sources and then calls\nsynchronize_irq() before the V3D is powered down. However, by itself,\nthis is not enough to quiesce the interrupt handler.\n\nsynchronize_irq() waits for handlers that have already set\nIRQD_IRQ_INPROGRESS, and for irqchips reporting IRQCHIP_STATE_ACTIVE.\nA GIC interrupt chip is able to mark an interrupt active as soon as a\nCPU acknowledges it, so there these checks cover the whole dispatch path.\nOn RPi 0-3, however, the interrupt controller is ARMCTRL, which has no\nactive state. A CPU that has read the hwirq out of the pending register\nbut has not yet reached handle_level_irq() stays invisible to\nsynchronize_irq().\n\nDuring a power transition, vc4_irq() may therefore run after the power\ndomain is off, where every V3D register read will return 0xdeadbeef.\n0xdeadbeef has FLDONE, FRDONE and OUTOMEM set.
