{"id":"AZL-100451","summary":"CVE-2026-89585 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nauxdisplay: charlcd: cancel backlight work on registration failure\n\nWith CONFIG_CHARLCD_BL_FLASH, charlcd_init() schedules bl_work before\ncharlcd_register() calls misc_register(). If registration fails, the\ncaller frees the charlcd object while delayed work still contains its\naddress.\n\nAdd charlcd_deinit() to cancel the delayed work and turn the backlight\noff. Use it for both registration rollback and normal unregistration.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:42Z","upstream":["CVE-2026-89585"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89585"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-100451.json"}}],"schema_version":"1.9.0"}
