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-2026-46011 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-46011/ (Markdown: https://insights.sbomify.com/CVE-2026-46011/index.md)","id":"CVE-2026-46011","markdown":"https://insights.sbomify.com/CVE-2026-46011/index.md","name":"CVE-2026-46011","record":{"aliases":["AZL-88629","BELL-CVE-2026-46011","DEBIAN-CVE-2026-46011","GHSA-cfrw-47v4-wfc7","ROOT-OS-UBUNTU-2404-CVE-2026-46011","UBUNTU-CVE-2026-46011"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's MediaTek JPEG driver allows attackers to execute arbitrary code or escalate privileges via a race condition.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: mtk-jpeg: fix use-after-free in release path due to uncancelled work\n\nThe mtk_jpeg_release() function frees the context structure (ctx) without\nfirst cancelling any pending or running work in ctx-\u003ejpeg_work. This\ncreates a race window where the workqueue callback may still be accessing\nthe context memory after it has been freed.\n\nRace condition:\n\n    CPU 0 (release)                    CPU 1 (workqueue)\n    ----------------                   ------------------\n    close()\n      mtk_jpeg_release()\n                                       mtk_jpegenc_worker()\n                                         ctx = work-\u003edata\n                                         // accessing ctx\n\n        kfree(ctx)  // freed!\n                                         access ctx  // UAF!\n\nThe work is queued via queue_work() during JPEG encode/decode operations\n(via mtk_jpeg_device_run). If the device is closed while work is pending\nor running, the work handler will access freed memory.\n\nFix this by calling cancel_work_sync() BEFORE acquiring the mutex. This\nordering is critical: if cancel_work_sync() is called after mutex_lock(),\nand the work handler also tries to acquire the same mutex, it would cause\na deadlock.\n\nNote: The open error path does NOT need cancel_work_sync() because\nINIT_WORK() only initializes the work structure - it does not schedule\nit. Work is only scheduled later during ioctl operations.","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":"media: mtk-jpeg: fix use-after-free in release path due to uncancelled work","id":"CVE-2026-46011","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"rxrpc: Fix memory leaks in rxkad_verify_response()","id":"CVE-2026-46012"},"packages":[],"prev":{"headline":"rxrpc: Fix error handling in rxgk_extract_token()","id":"CVE-2026-46010"},"products":["Linux"],"published":"2026-05-27","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's MediaTek JPEG driver allows attackers to execute arbitrary code or escalate privileges via a race condition.","url":"https://insights.sbomify.com/CVE-2026-46011/"}
