{"id":"DEBIAN-CVE-2023-52979","details":"In the Linux kernel, the following vulnerability has been resolved:  squashfs: harden sanity check in squashfs_read_xattr_id_table  While mounting a corrupted filesystem, a signed integer '*xattr_ids' can become less than zero.  This leads to the incorrect computation of 'len' and 'indexes' values which can cause null-ptr-deref in copy_bio_to_actor() or out-of-bounds accesses in the next sanity checks inside squashfs_read_xattr_id_table().  Found by Linux Verification Center (linuxtesting.org) with Syzkaller.","modified":"2025-11-04T14:12:27.329377Z","published":"2025-03-27T17:15:45Z","withdrawn":"2025-11-04T14:12:27.329377Z","upstream":["CVE-2023-52979"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-52979"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:11","purl":"pkg:deb/debian/linux?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.178-1"}]}],"versions":["5.10.103-1","5.10.103-1~bpo10+1","5.10.106-1","5.10.113-1","5.10.120-1","5.10.120-1~bpo10+1","5.10.127-1","5.10.127-2","5.10.127-2~bpo10+1","5.10.136-1","5.10.140-1","5.10.148-1","5.10.149-1","5.10.149-2","5.10.158-1","5.10.158-2","5.10.162-1","5.10.46-4","5.10.46-5","5.10.70-1","5.10.70-1~bpo10+1","5.10.84-1","5.10.92-1","5.10.92-1~bpo10+1","5.10.92-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52979.json"}},{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52979.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52979.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52979.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
