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-2026-99003/ (Markdown: https://insights.sbomify.com/CVE-2026-99003/index.md)","id":"CVE-2026-99003","markdown":"https://insights.sbomify.com/CVE-2026-99003/index.md","name":"CVE-2026-99003","record":{"aliases":["BELL-CVE-2026-99003","DEBIAN-CVE-2026-99003","GHSA-chr3-6fxw-gjw4","UBUNTU-CVE-2026-99003"],"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/panthor: validate userspace queue count against initialized firmware slot count\n\nIn panthor_drv.c:panthor_ioctl_group_create(),\nthe queue count is validated against the hardcoded maximum:\n\n\tif (!args-\u003equeues.count || args-\u003equeues.count \u003e MAX_CS_PER_CSG)\n\t\treturn -EINVAL;\n\nHowever, if the firmware reports fewer slots than MAX_CS_PER_CSG,\npanthor_fw_init_ifaces() will only initialize that smaller number of\nstream interfaces.\n\nIf unprivileged userspace requests more queues than the firmware reported\n(but no more than MAX_CS_PER_CSG), cs_slot_prog_locked() fetches an\nuninitialized stream interface and may crash when dereferencing\ncs_iface-\u003einput-\u003eringbuf_base.","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":"drm/panthor: validate userspace queue count against initialized firmware slot count","id":"CVE-2026-99003","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"drm/imagination: Size page table preallocation by device address","id":"CVE-2026-99004"},"packages":[],"prev":{"headline":"drm/vmwgfx: validate pitch coming from userspace","id":"CVE-2026-99002"},"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":"2026-10-23","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-99003/"}
