{"id":"AZL-80601","summary":"CVE-2026-23388 affecting package kernel for versions less than 6.6.130.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nSquashfs: check metadata block offset is within range\n\nSyzkaller reports a \"general protection fault in squashfs_copy_data\"\n\nThis is ultimately caused by a corrupted index look-up table, which\nproduces a negative metadata block offset.\n\nThis is subsequently passed to squashfs_copy_data (via\nsquashfs_read_metadata) where the negative offset causes an out of bounds\naccess.\n\nThe fix is to check that the offset is within range in\nsquashfs_read_metadata.  This will trap this and other cases.","modified":"2026-08-28T17:46:33.985342087Z","published":"2026-03-25T11:16:39Z","upstream":["CVE-2026-23388"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23388"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.130.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-80601.json"}}],"schema_version":"1.9.0"}
