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-2022-48945 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-2022-48945/ (Markdown: https://insights.sbomify.com/CVE-2022-48945/index.md)","id":"CVE-2022-48945","markdown":"https://insights.sbomify.com/CVE-2022-48945/index.md","name":"CVE-2022-48945","record":{"aliases":["DEBIAN-CVE-2022-48945","GHSA-g3vj-v55c-g2x7","UBUNTU-CVE-2022-48945"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A boundary check error in the Linux kernel vivid driver allows a local attacker to cause a kernel crash via a page fault.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":[],"description":"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) - not-present page\n PGD 100000067 P4D 100000067 PUD 10015f067 PMD 1121ca067 PTE 0\n Oops: 0002 [#1] PREEMPT SMP\n CPU: 0 PID: 23489 Comm: vivid-000-vid-c Not tainted 6.1.0-rc1+ #512\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014\n RIP: 0010:memcpy_erms+0x6/0x10\n[...]\n Call Trace:\n  \u003cTASK\u003e\n  ? tpg_fill_plane_buffer+0x856/0x15b0\n  vivid_fillbuff+0x8ac/0x1110\n  vivid_thread_vid_cap_tick+0x361/0xc90\n  vivid_thread_vid_cap+0x21a/0x3a0\n  kthread+0x143/0x180\n  ret_from_fork+0x1f/0x30\n  \u003c/TASK\u003e\n\nThis is because we forget to check boundary after adjust compose-\u003eheight\nint V4L2_SEL_TGT_CROP case.
