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-2026-98878/ (Markdown: https://insights.sbomify.com/CVE-2026-98878/index.md)","id":"CVE-2026-98878","markdown":"https://insights.sbomify.com/CVE-2026-98878/index.md","name":"CVE-2026-98878","record":{"aliases":["AZL-110558","BELL-CVE-2026-98878","DEBIAN-CVE-2026-98878","GHSA-w79p-wpg5-4m55","UBUNTU-CVE-2026-98878"],"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\nirqchip/gic-v5: Immediately exec priority drop following activate\n\nWith GICv5 an interrupt of equal or lower priority cannot be signalled\nuntil there has been a priority drop. This is done via the GIC CDEOI\nsystem instruction. Once this has been executed, the hardware is able\nto signal the next interrupt if there is one.\n\nAs all interrupts are programmed to have the same priority, no new\ninterrupts can be signalled until the priority drop has happened. This\ncan cause issues when, for example, an interrupt remains active while\na long running process takes place, such as when injecting a physical\ninterrupt into a guest VM in software.\n\nThe GICv5 driver has so far done the priority drop as part of\nirq_eoi(), i.e., at the same time as deactivating the interrupt. This\nmeans that any long running process (or VM) could block incoming\ninterrupts, effectively causing a denial of service for all other\ninterrupts.\n\nRather than doing the EOI as part of irq_eoi() (which the name would\nsuggest would be a good place for it), move it to happen immediately\nafter acknowledging an interrupt in the main GICv5 interrupt\nhandler.
