If altr_sysmgr_regmap_lookup_by_phandle() returns -EPROBE_DEFER, the\nprobe is deferred until after __init memory is freed.\"\n\nThe a10 EDAC .setup callbacks (sdmmc, ethernet, nand, dma, usb, qspi) and\ntheir helpers (altr_init_a10_ecc_device_type, altr_init_a10_ecc_block) were\nmarked __init. These run from the probe path, which may execute after init\nmemory is freed -- e.g. a probe deferred via -EPROBE_DEFER that only succeeds\nonce a late/module dependency appears, or a manual unbind/rebind. Calling\n__init code then dereferences freed memory. Remove __init so these functions\nremain valid at runtime.","state":0,"publishedAt":"2026-10-18T15:47:24.602+00:00","modifiedAt":"2026-10-19T09:24:50.943+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/edac/altera_edac.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"788586efd116d6d7d05985881eda503333e702b4\",\n                            \"lessThan\": \"9846b85c2eb8b749c3f14bdcc31b1070f6aabba8\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"788586efd116d6d7d05985881eda503333e702b4\",\n                            \"lessThan\": \"4ec26cb7984740941892ad21fa974963c198bfaa\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"788586efd116d6d7d05985881eda503333e702b4\",\n                            \"lessThan\": \"b62a264163ca51bee04785c581344751812395df\",\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/edac/altera_edac.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"5.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.56\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.10\",\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":[],"references":["https://git.kernel.org/stable/c/9846b85c2eb8b749c3f14bdcc31b1070f6aabba8","https://git.kernel.org/stable/c/4ec26cb7984740941892ad21fa974963c198bfaa","https://git.kernel.org/stable/c/b62a264163ca51bee04785c581344751812395df"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98740","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98740","identifiers":["CVE-2026-98740"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
