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-2024-26607 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-2024-26607/ (Markdown: https://insights.sbomify.com/CVE-2024-26607/index.md)","id":"CVE-2024-26607","markdown":"https://insights.sbomify.com/CVE-2024-26607/index.md","name":"CVE-2024-26607","record":{"aliases":["AZL-55250","BELL-CVE-2024-26607","DEBIAN-CVE-2024-26607","GHSA-3659-jjmv-v338","ROOT-OS-DEBIAN-11-CVE-2024-26607","UBUNTU-CVE-2024-26607"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DRM driver","requires_auth":"low_privilege","summary":"A race condition in the sii902x DRM bridge driver causes a null pointer dereference, leading to a kernel crash on affected Linux systems.","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":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/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/bridge: sii902x: Fix probing race issue\n\nA null pointer dereference crash has been observed rarely on TI\nplatforms using sii9022 bridge:\n\n[   53.271356]  sii902x_get_edid+0x34/0x70 [sii902x]\n[   53.276066]  sii902x_bridge_get_edid+0x14/0x20 [sii902x]\n[   53.281381]  drm_bridge_get_edid+0x20/0x34 [drm]\n[   53.286305]  drm_bridge_connector_get_modes+0x8c/0xcc [drm_kms_helper]\n[   53.292955]  drm_helper_probe_single_connector_modes+0x190/0x538 [drm_kms_helper]\n[   53.300510]  drm_client_modeset_probe+0x1f0/0xbd4 [drm]\n[   53.305958]  __drm_fb_helper_initial_config_and_unlock+0x50/0x510 [drm_kms_helper]\n[   53.313611]  drm_fb_helper_initial_config+0x48/0x58 [drm_kms_helper]\n[   53.320039]  drm_fbdev_dma_client_hotplug+0x84/0xd4 [drm_dma_helper]\n[   53.326401]  drm_client_register+0x5c/0xa0 [drm]\n[   53.331216]  drm_fbdev_dma_setup+0xc8/0x13c [drm_dma_helper]\n[   53.336881]  tidss_probe+0x128/0x264 [tidss]\n[   53.341174]  platform_probe+0x68/0xc4\n[   53.344841]  really_probe+0x188/0x3c4\n[   53.348501]  __driver_probe_device+0x7c/0x16c\n[   53.352854]  driver_probe_device+0x3c/0x10c\n[   53.357033]  __device_attach_driver+0xbc/0x158\n[   53.361472]  bus_for_each_drv+0x88/0xe8\n[   53.365303]  __device_attach+0xa0/0x1b4\n[   53.369135]  device_initial_probe+0x14/0x20\n[   53.373314]  bus_probe_device+0xb0/0xb4\n[   53.377145]  deferred_probe_work_func+0xcc/0x124\n[   53.381757]  process_one_work+0x1f0/0x518\n[   53.385770]  worker_thread+0x1e8/0x3dc\n[   53.389519]  kthread+0x11c/0x120\n[   53.392750]  ret_from_fork+0x10/0x20\n\nThe issue here is as follows:\n\n- tidss probes, but is deferred as sii902x is still missing.\n- sii902x starts probing and enters sii902x_init().\n- sii902x calls drm_bridge_add().
