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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/edac/altera_edac.c"],"versions":[{"version":"788586efd116d6d7d05985881eda503333e702b4","lessThan":"9846b85c2eb8b749c3f14bdcc31b1070f6aabba8","status":"affected","versionType":"git"},{"version":"788586efd116d6d7d05985881eda503333e702b4","lessThan":"4ec26cb7984740941892ad21fa974963c198bfaa","status":"affected","versionType":"git"},{"version":"788586efd116d6d7d05985881eda503333e702b4","lessThan":"b62a264163ca51bee04785c581344751812395df","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/edac/altera_edac.c"],"versions":[{"version":"5.2","status":"affected"},{"version":"0","lessThan":"5.2","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"6.18.56"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"7.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9846b85c2eb8b749c3f14bdcc31b1070f6aabba8"},{"url":"https://git.kernel.org/stable/c/4ec26cb7984740941892ad21fa974963c198bfaa"},{"url":"https://git.kernel.org/stable/c/b62a264163ca51bee04785c581344751812395df"}],"title":"EDAC/altera: Drop __init from ECC setup paths for re-probe safety","x_generator":{"engine":"bippy-1.2.0"}}}}
