{"id":"DEBIAN-CVE-2022-50830","details":"In the Linux kernel, the following vulnerability has been resolved:  auxdisplay: hd44780: Fix potential memory leak in hd44780_remove()  hd44780_probe() allocates a memory chunk for hd with kzalloc() and makes \"lcd-\u003edrvdata-\u003ehd44780\" point to it. When we call hd44780_remove(), we should release all relevant memory and resource. But \"lcd-\u003edrvdata -\u003ehd44780\" is not released, which will lead to a memory leak.  We should release the \"lcd-\u003edrvdata-\u003ehd44780\" in hd44780_remove() to fix the memory leak bug.","modified":"2026-08-27T22:47:32.813221991Z","published":"2025-12-30T13:15:57.490Z","upstream":["CVE-2022-50830"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-50830"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50830.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50830.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-50830.json"}}],"schema_version":"1.9.0"}
