{"id":"AZL-100584","summary":"CVE-2026-89618 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\neventfs: Initialize ei-\u003echildren and ei-\u003elist in init_ei()\n\neventfs_create_dir() allocates the eventfs_inode and initializes it with\ninit_ei(). But this does not initialize the eventfs_inode list_heads. If\nthe eventfs_create_dir() fails due to memory pressure, it will call\nfree_ei() before it initialized the lists, and that checks to make sure\nthe eventfs_inode has no children. But because the list wasn't\ninitialized, it will give a false warning.\n\nFix it by moving the list initialization into init_ei().\n\n[ Rewrote change log ]","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:47Z","upstream":["CVE-2026-89618"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89618"}],"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-100584.json"}}],"schema_version":"1.9.0"}
