When we call hd44780_remove(),\nwe should release all relevant memory and resource. But \"lcd-\u003edrvdata\n-\u003ehd44780\" is not released, which will lead to a memory leak.\n\nWe should release the \"lcd-\u003edrvdata-\u003ehd44780\" in hd44780_remove() to fix\nthe memory leak bug.","modified":"2026-04-02T08:28:46.984508Z","published":"2025-12-30T12:10:52.099Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0617-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50830.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5d407911e605702ffcc0e97a6db546592ab27dd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6cd37f8232f5e169a723e1d5fbe3b2139c2ef763"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8311961a1724bfc64390c539dedc31e067a80315"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ddf75a86aba2cfb7ec4497e8692b60c8c8fe0ee7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50830.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50830"},{"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":"718e05ed92ecac0d9d3954bcc8064527c3ce7565"},{"fixed":"8311961a1724bfc64390c539dedc31e067a80315"},{"fixed":"6cd37f8232f5e169a723e1d5fbe3b2139c2ef763"},{"fixed":"5d407911e605702ffcc0e97a6db546592ab27dd0"},{"fixed":"ddf75a86aba2cfb7ec4497e8692b60c8c8fe0ee7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50830.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.100"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.18"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50830.json"}}],"schema_version":"1.7.5"}
