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-2022-50725 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2022-50725/ (Markdown: https://insights.sbomify.com/CVE-2022-50725/index.md)","id":"CVE-2022-50725","markdown":"https://insights.sbomify.com/CVE-2022-50725/index.md","name":"CVE-2022-50725","record":{"aliases":["DEBIAN-CVE-2022-50725","GHSA-jx9q-5j85-6qhg","UBUNTU-CVE-2022-50725"],"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 media driver","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel vidtv driver allows local attackers to execute arbitrary code or escalate privileges via improper error handling.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: vidtv: Fix use-after-free in vidtv_bridge_dvb_init()\n\nKASAN reports a use-after-free:\nBUG: KASAN: use-after-free in dvb_dmxdev_release+0x4d5/0x5d0 [dvb_core]\nCall Trace:\n ...\n dvb_dmxdev_release+0x4d5/0x5d0 [dvb_core]\n vidtv_bridge_probe+0x7bf/0xa40 [dvb_vidtv_bridge]\n platform_probe+0xb6/0x170\n ...\nAllocated by task 1238:\n ...\n dvb_register_device+0x1a7/0xa70 [dvb_core]\n dvb_dmxdev_init+0x2af/0x4a0 [dvb_core]\n vidtv_bridge_probe+0x766/0xa40 [dvb_vidtv_bridge]\n ...\nFreed by task 1238:\n dvb_register_device+0x6d2/0xa70 [dvb_core]\n dvb_dmxdev_init+0x2af/0x4a0 [dvb_core]\n vidtv_bridge_probe+0x766/0xa40 [dvb_vidtv_bridge]\n ...\n\nIt is because the error handling in vidtv_bridge_dvb_init() is wrong.\n\nFirst, vidtv_bridge_dmx(dev)_init() will clean themselves when fail, but\ngoto fail_dmx(_dev): calls release functions again, which causes\nuse-after-free.\n\nAlso, in fail_fe, fail_tuner_probe and fail_demod_probe, j = i will cause\nout-of-bound when i finished its loop (i == NUM_FE).
