It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90192 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-90192/ (Markdown: https://insights.sbomify.com/CVE-2026-90192/index.md)","id":"CVE-2026-90192","markdown":"https://insights.sbomify.com/CVE-2026-90192/index.md","name":"CVE-2026-90192","record":{"aliases":["BELL-CVE-2026-90192","DEBIAN-CVE-2026-90192","GHSA-39h4-xrh5-39fg","UBUNTU-CVE-2026-90192"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A NULL pointer dereference in the Qualcomm CPUCP mailbox driver causes a kernel panic when clearing channels under PREEMPT_RT, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","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\nmailbox: qcom-cpucp: handle NULL data in send_data callback\n\nmailbox_clear_channel() calls mbox_send_message() with NULL data to\nnotify the remote side that the RX channel has been cleared.\nqcom_cpucp_mbox_send_data() blindly dereferenced the data pointer,\ncausing a NULL pointer dereference kernel panic when invoked from\nthis path under PREEMPT_RT.\n\nAdd an explicit NULL check and return early without writing to the\nTX register, which is the correct behaviour for a channel-clear\nnotification.","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":"mailbox: qcom-cpucp: handle NULL data in send_data callback","id":"CVE-2026-90192","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"mailbox: qcom-cpucp: fix PREEMPT_RT self-deadlock in IRQ handler","id":"CVE-2026-90193"},"packages":[],"prev":{"headline":"mailbox: riscv-sbi-mpxy: validate RPMI notification lengths","id":"CVE-2026-90191"},"products":["Linux"],"published":"2026-09-17","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":"2026-10-19","vendors":["Linux"]},"summary":"A NULL pointer dereference in the Qualcomm CPUCP mailbox driver causes a kernel panic when clearing channels under PREEMPT_RT, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-90192/"}
