{"id":"AZL-77745","summary":"CVE-2026-23141 affecting package kernel for versions less than 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: send: check for inline extents in range_is_hole_in_parent()\n\nBefore accessing the disk_bytenr field of a file extent item we need\nto check if we are dealing with an inline extent.\nThis is because for inline extents their data starts at the offset of\nthe disk_bytenr field. So accessing the disk_bytenr\nmeans we are accessing inline data or in case the inline data is less\nthan 8 bytes we can actually cause an invalid\nmemory access if this inline extent item is the first item in the leaf\nor access metadata from other items.","modified":"2026-08-28T17:47:51.362130673Z","published":"2026-02-14T16:15:54Z","upstream":["CVE-2026-23141"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23141"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-77745.json"}}],"schema_version":"1.9.0"}
