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-2026-98877/ (Markdown: https://insights.sbomify.com/CVE-2026-98877/index.md)","id":"CVE-2026-98877","markdown":"https://insights.sbomify.com/CVE-2026-98877/index.md","name":"CVE-2026-98877","record":{"aliases":["AZL-110605","BELL-CVE-2026-98877","DEBIAN-CVE-2026-98877","GHSA-32qr-g6m6-8v7x","UBUNTU-CVE-2026-98877"],"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-v4: Don't advertise VLPIs if no ITS is probed\n\nWhen accidentally setting “kvm-arm.vgic_v4_enable=1” on a system that has\nno MSI controller device tree node and GICv4, it results a panic as\n“gic_domain” is NULL and the kernel attempts to access it.\n\n    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028\n    Mem abort info:\n      ESR = 0x0000000096000006\n\n    CPU: 1 UID: 0 PID: 295 Comm: lkvm-static Not tainted 7.1.0-rc4-ge3f15ad3970e #5 PREEMPT\n    Hardware name: linux,dummy-virt (DT)\n    pstate: 81402005 (Nzcv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\n    pc : __irq_domain_instantiate+0x1d4/0x578\n    lr : __irq_domain_instantiate+0x1cc/0x578\n\nSet vLPI support to false at init time if the host has no ITS, so it\npropagates properly to kvm_vgic_global_state.has_gicv4.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed","id":"CVE-2026-98877","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"irqchip/gic-v5: Immediately exec priority drop following activate","id":"CVE-2026-98878"},"packages":[],"prev":{"headline":"host1x: bus: Fix missing ops null check in error teardown","id":"CVE-2026-98876"},"products":["Linux"],"published":"2026-10-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-26","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-98877/"}
