At this time,\nthe pointer may no longer be valid.\n\nEvent injection can be used to trigger a crash:\n\n$ cd /sys/kernel/tracing\n$ echo 'value = 0' > events/fsl_edma/edma_writeb/inject\n$ cat trace\n\nThe log output needs only edma->membase. Add a membase field at the end\nof the event and use the new field for log output. Keep the existing\nfields for backward compatibility.","state":0,"publishedAt":"2026-09-16T10:33:07.292+00:00","modifiedAt":"2026-10-19T08:56:08.384+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/dma/fsl-edma-trace.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"11102d0c343ba06ddd303f2503c0ce46d70052f2\",\n                            \"lessThan\": \"ef02cd3807f39ae1dbc924788d8fa6a85334c435\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"11102d0c343ba06ddd303f2503c0ce46d70052f2\",\n                            \"lessThan\": \"d382aaf5fed38c6dd2e0cc710d97cb81d660ffa7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"11102d0c343ba06ddd303f2503c0ce46d70052f2\",\n                            \"lessThan\": \"2a3801ae5c344473e648006c5b03a9216ac54a6a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"11102d0c343ba06ddd303f2503c0ce46d70052f2\",\n                            \"lessThan\": \"2ea04dca8e627f722caa7a2037cfbae0257f3501\",\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/dma/fsl-edma-trace.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.10\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.110\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.51\",\n                            \"lessThanOrEqual\": \"6.18.*\",\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/ef02cd3807f39ae1dbc924788d8fa6a85334c435","https://git.kernel.org/stable/c/d382aaf5fed38c6dd2e0cc710d97cb81d660ffa7","https://git.kernel.org/stable/c/2a3801ae5c344473e648006c5b03a9216ac54a6a","https://git.kernel.org/stable/c/2ea04dca8e627f722caa7a2037cfbae0257f3501"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89994","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89994","identifiers":["CVE-2026-89994"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
