{"id":"AZL-52523","summary":"CVE-2024-50116 affecting package kernel for versions less than 6.6.64.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix kernel bug due to missing clearing of buffer delay flag\n\nSyzbot reported that after nilfs2 reads a corrupted file system image\nand degrades to read-only, the BUG_ON check for the buffer delay flag\nin submit_bh_wbc() may fail, causing a kernel bug.\n\nThis is because the buffer delay flag is not cleared when clearing the\nbuffer state flags to discard a page/folio or a buffer head. So, fix\nthis.\n\nThis became necessary when the use of nilfs2's own page clear routine\nwas expanded.  This state inconsistency does not occur if the buffer\nis written normally by log writing.","modified":"2026-04-01T05:17:51.771428Z","published":"2024-11-05T18:15:14Z","upstream":["CVE-2024-50116"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50116"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-52523.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
