qrtr_ns_data_ready() callback will\ntry to queue the work, causing use-after-free issue.\n\nFix this issue by saving the default 'sk_data_ready' callback during\nqrtr_ns_init() and use it to replace the qrtr_ns_data_ready() callback at\nthe start of remove(). This ensures that even if a packet arrives after\ndestroy_workqueue(), the work struct will not be dereferenced.\n\nNote that it is also required to ensure that the RX threads are completed\nbefore destroying the workqueue, because the threads could be using the\nqrtr_ns_data_ready() callback."}], "lastModified": "2026-06-17T10:52:57.673", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "33983DD1-6F5C-4A20-A9AF-24DABFA46B60", "versionEndExcluding": "5.10.258", "versionStartIncluding": "5.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "919C10A9-7951-4A74-BADD-C135A0A8D8B4", "versionEndExcluding": "5.15.209", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "92385813-D91D-480D-83A1-F423D2CBB2BA", "versionEndExcluding": "6.1.175", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A1A92866-F406-43B5-B2D1-CFC274753E9D", "versionEndExcluding": "6.6.140", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "55DA1C62-9991-451E-B8A8-E0004E00F789", "versionEndExcluding": "6.12.86", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A10AC84F-C058-47D5-85B4-E6E51A613B74", "versionEndExcluding": "6.18.27", "versionStartIncluding": "6.13"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CDB78D6D-22C3-4154-B0D0-94AF1CE5C2E3", "versionEndExcluding": "7.0.4", "versionStartIncluding": "6.19"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
