{"id":"CVE-2026-23141","summary":"btrfs: send: check for inline extents in range_is_hole_in_parent()","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":"2026-04-02T17:30:12.911342594Z","published":"2026-02-14T15:36:07.417Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1041-1","SUSE-SU-2026:1078-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23141.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/08b096c1372cd69627f4f559fb47c9fb67a52b39"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39f83f10772310ba4a77f2b5256aaf36994ef7e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d948055bd46a9c14d1d4217aed65c5c258c32903"},{"type":"WEB","url":"https://git.kernel.org/stable/c/db00636643e66898d79f2530ac9c56ebd5eca369"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2dc6ab3a14c2d2eb0b14783427eb9b03bf631c9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23141.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23141"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"82bfb2e7b645c8f228dc3b6d3b27b0b10125ca4f"},{"fixed":"d948055bd46a9c14d1d4217aed65c5c258c32903"},{"fixed":"f2dc6ab3a14c2d2eb0b14783427eb9b03bf631c9"},{"fixed":"db00636643e66898d79f2530ac9c56ebd5eca369"},{"fixed":"39f83f10772310ba4a77f2b5256aaf36994ef7e8"},{"fixed":"08b096c1372cd69627f4f559fb47c9fb67a52b39"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23141.json"}}],"schema_version":"1.7.5"}
