Title
media: vivid: fix compose size exceed boundary
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: vivid: fix compose size exceed boundary
syzkaller found a bug:
BUG: unable to handle page fault for address: ffffc9000a3b1000
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
PGD 100000067 P4D 100000067 PUD 10015f067 PMD 1121ca067 PTE 0

Heap/vmalloc memory corruption from the oversized compose write is leverageable for kernel information disclosure (same class as CVE-2025-38226), and related loop/copy paths can surface adjacent data into attacker-readable capture buffers.\\nI:H - This is an attacker-triggered out-of-bounds write in tpg_fill_plane_buffer (memcpy past the allocated frame buffer via compose.top/height/left), a classic heap corruption primitive suitable for control-flow hijacking.\\nA:H - The demonstrated effect is a kernel oops (supervisor write page fault in memcpy_erms during tpg_fill_plane_buffer in the vivid kthread), which can panic the machine and is re-triggerable at will.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"8c0ee15d9a102c732d0745566d254040085d5663\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"5edc3604151919da8da0fb092b71d7dce07d848a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"9c7fba9503b826f0c061d136f8f0c9f953ed18b9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"54f259906039dbfe46c550011409fa16f72370f6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"f9d19f3a044ca651b0be52a4bf951ffe74259b9f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"ab54081a2843aefb837812fac5488cc8f1696142\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"ccb5392c4fea0e7d9f7ab35567e839d74cb3998b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"2f558c5208b0f70c8140e08ce09fcc84da48e789\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef834f7836ec0502f49f20bbc42f1240577a9c83\", \"lessThan\": \"94a7ad9283464b75b12516c5512541d467cefcf8\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/media/test-drivers/vivid/vivid-vid-cap.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.18\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.18\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.9.337\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.9.*\"}, {\"status\": \"unaffected\", \"version\": \"4.14.303\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.14.*\"}, {\"status\": \"unaffected\", \"version\": \"4.19.270\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.229\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.163\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.86\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.0.16\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.0.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.2\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/media/test-drivers/vivid/vivid-vid-cap.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/8c0ee15d9a102c732d0745566d254040085d5663\"}, {\"url\": \"https://git.kernel.org/stable/c/5edc3604151919da8da0fb092b71d7dce07d848a\"}, {\"url\": \"https://git.kernel.org/stable/c/9c7fba9503b826f0c061d136f8f0c9f953ed18b9\"}, {\"url\": \"https://git.kernel.org/stable/c/54f259906039dbfe46c550011409fa16f72370f6\"}, {\"url\": \"https://git.kernel.org/stable/c/f9d19f3a044ca651b0be52a4bf951ffe74259b9f\"}, {\"url\": \"https://git.kernel.org/stable/c/ab54081a2843aefb837812fac5488cc8f1696142\"}, {\"url\": \"https://git.kernel.org/stable/c/ccb5392c4fea0e7d9f7ab35567e839d74cb3998b\"}, {\"url\": \"https://git.kernel.org/stable/c/2f558c5208b0f70c8140e08ce09fcc84da48e789\"}, {\"url\": \"https://git.kernel.org/stable/c/94a7ad9283464b75b12516c5512541d467cefcf8\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nmedia: vivid: fix compose size exceed boundary\\n\\nsyzkaller found a bug:\\n\\n BUG: unable to handle page fault for address: ffffc9000a3b1000\\n #PF: supervisor write access in kernel mode\\n #PF: error_code(0x0002) -

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
