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-2024-43899 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-2024-43899/ (Markdown: https://insights.sbomify.com/CVE-2024-43899/index.md)","id":"CVE-2024-43899","markdown":"https://insights.sbomify.com/CVE-2024-43899/index.md","name":"CVE-2024-43899","record":{"aliases":["AZL-48209","AZL-48234","BELL-CVE-2024-43899","DEBIAN-CVE-2024-43899","GHSA-76rf-j9m6-mjgj","ROOT-OS-DEBIAN-11-CVE-2024-43899","ROOT-OS-DEBIAN-12-CVE-2024-43899","ROOT-OS-UBUNTU-2204-CVE-2024-43899","UBUNTU-CVE-2024-43899"],"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 null pointer dereference in the Linux kernel AMD display driver causes a system hang when playing video in fullscreen mode.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix null pointer deref in dcn20_resource.c\n\nFixes a hang thats triggered when MPV is run on a DCN401 dGPU:\n\nmpv --hwdec=vaapi --vo=gpu --hwdec-codecs=all\n\nand then enabling fullscreen playback (double click on the video)\n\nThe following calltrace will be seen:\n\n[  181.843989] BUG: kernel NULL pointer dereference, address: 0000000000000000\n[  181.843997] #PF: supervisor instruction fetch in kernel mode\n[  181.844003] #PF: error_code(0x0010) - not-present page\n[  181.844009] PGD 0 P4D 0\n[  181.844020] Oops: 0010 [#1] PREEMPT SMP NOPTI\n[  181.844028] CPU: 6 PID: 1892 Comm: gnome-shell Tainted: G        W  OE      6.5.0-41-generic #41~22.04.2-Ubuntu\n[  181.844038] Hardware name: System manufacturer System Product Name/CROSSHAIR VI HERO, BIOS 6302 10/23/2018\n[  181.844044] RIP: 0010:0x0\n[  181.844079] Code: Unable to access opcode bytes at 0xffffffffffffffd6.\n[  181.844084] RSP: 0018:ffffb593c2b8f7b0 EFLAGS: 00010246\n[  181.844093] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000004\n[  181.844099] RDX: ffffb593c2b8f804 RSI: ffffb593c2b8f7e0 RDI: ffff9e3c8e758400\n[  181.844105] RBP: ffffb593c2b8f7b8 R08: ffffb593c2b8f9c8 R09: ffffb593c2b8f96c\n[  181.844110] R10: 0000000000000000 R11: 0000000000000000 R12: ffffb593c2b8f9c8\n[  181.844115] R13: 0000000000000001 R14: ffff9e3c88000000 R15: 0000000000000005\n[  181.844121] FS:  00007c6e323bb5c0(0000) GS:ffff9e3f85f80000(0000) knlGS:0000000000000000\n[  181.844128] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  181.844134] CR2: ffffffffffffffd6 CR3: 0000000140fbe000 CR4: 00000000003506e0\n[  181.844141] Call Trace:\n[  181.844146]  \u003cTASK\u003e\n[  181.844153]  ?
