{"id":"CVE-2022-50618","summary":"mmc: meson-gx: fix return value check of mmc_add_host()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: meson-gx: fix return value check of mmc_add_host()\n\nmmc_add_host() may return error, if we ignore its return value,\nit will lead two issues:\n1. The memory that allocated in mmc_alloc_host() is leaked.\n2. In the remove() path, mmc_remove_host() will be called to\n   delete device, but it's not added yet, it will lead a kernel\n   crash because of null-ptr-deref in device_del().\n\nFix this by checking the return value and goto error path which\nwill call mmc_free_host().","modified":"2026-04-02T08:28:39.822252Z","published":"2025-12-08T01:16:31.649Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0617-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50618.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/42343e3c6195e934b9cb4c08b7ff84a3778d77f9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64b2c441171febf075bd9632aca579afda8ab9fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/90935f16f2650ab7416fa2ffbe5c28cb39cf3f1e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e11c6bb745be4e9b325cf96031b4ea34801342d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0cfe7aa41f3965f5224affd88afd48c60f6ad1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f5506e0bbb25102bd8ef2e1a3b483a0b934e454e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f5ce76aeddf01ca8f2a80fc37119388d59db7c10"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50618.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50618"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"51c5d8447bd71b7e539c19c46a03b73c0e91fa66"},{"fixed":"f5506e0bbb25102bd8ef2e1a3b483a0b934e454e"},{"fixed":"9e11c6bb745be4e9b325cf96031b4ea34801342d"},{"fixed":"64b2c441171febf075bd9632aca579afda8ab9fb"},{"fixed":"e0cfe7aa41f3965f5224affd88afd48c60f6ad1f"},{"fixed":"42343e3c6195e934b9cb4c08b7ff84a3778d77f9"},{"fixed":"f5ce76aeddf01ca8f2a80fc37119388d59db7c10"},{"fixed":"90935f16f2650ab7416fa2ffbe5c28cb39cf3f1e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50618.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"4.19.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.229"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.163"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50618.json"}}],"schema_version":"1.7.5"}
