Both keep touching stream, port\nand device state; the recovery worker also resets the parser and VPDMA,\nrepopulates the descriptor list, and re-enables the per-list IRQs.\n\nvip_stop_streaming() masks and clears the per-list IRQs, but it neither\nsynchronizes the hardirq handler nor disables recovery_work. An overflow\nIRQ that has already queued recovery_work, or a list-complete IRQ in\nflight when the stream is torn down, can therefore still dereference the\nstream after its resources are released: the descriptor list is freed by\nvip_release_stream() on file release, and the stream itself by\nfree_stream() on unbind/remove.\n\nDrain the recovery worker and the IRQ handler at both teardown points\nthrough a shared vip_quiesce_stream() helper, before any stream-owned\nresource is released. disable_work_sync() cancels pending recovery_work,\ndrains a running instance, and raises its disable depth, so a subsequent\nschedule_work() issued by a racing IRQ handler is rejected at the\nworkqueue scheduler: recovery_work cannot be requeued after\ndisable_work_sync() takes effect. The worker may still re-enable the\nper-list IRQs before disable_work_sync() returns; disable_irqs() then\nmasks those sources and synchronize_irq() waits for any in-flight handler\nthat still dereferences stream state. In vip_stop_streaming() the helper\nruns before the parser is stopped, since a worker drained by\ndisable_work_sync() may re-enable the parser before exiting and would\notherwise undo the stop. recovery_work is created disabled and enabled in\nvip_start_streaming() before IRQs, pairing the enable with the teardown\ndisable across the streaming lifecycle.\n\nThis issue was found by an in-house static analysis tool and confirmed\nby manual code review.","state":0,"publishedAt":"2026-09-16T10:31:42.777+00:00","modifiedAt":"2026-10-19T08:54:08.215+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/media/platform/ti/vpe/vip.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"fc2873aa4a21355593b55eb49ff534d31f81c584\",\n                            \"lessThan\": \"fd5b4a14c87b21e1c9eaee603b01bb7fa7db45c8\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"fc2873aa4a21355593b55eb49ff534d31f81c584\",\n                            \"lessThan\": \"aeaacc3001449d44b4ab7da56331121d1f3b137b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/media/platform/ti/vpe/vip.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.5\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/fd5b4a14c87b21e1c9eaee603b01bb7fa7db45c8","https://git.kernel.org/stable/c/aeaacc3001449d44b4ab7da56331121d1f3b137b"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89875","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89875","identifiers":["CVE-2026-89875"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
