{"id":"DEBIAN-CVE-2023-54272","details":"In the Linux kernel, the following vulnerability has been resolved:  fs/ntfs3: Fix a possible null-pointer dereference in ni_clear()  In a previous commit c1006bd13146, ni-\u003emi.mrec in ni_write_inode() could be NULL, and thus a NULL check is added for this variable.  However, in the same call stack, ni-\u003emi.mrec can be also dereferenced in ni_clear():  ntfs_evict_inode(inode)   ni_write_inode(inode, ...)     ni = ntfs_i(inode);     is_rec_inuse(ni-\u003emi.mrec) -\u003e Add a NULL check by previous commit   ni_clear(ntfs_i(inode))     is_rec_inuse(ni-\u003emi.mrec) -\u003e No check  Thus, a possible null-pointer dereference may exist in ni_clear(). To fix it, a NULL check is added in this function.","modified":"2026-09-15T08:47:33.136389553Z","published":"2025-12-30T13:16:16.110Z","upstream":["CVE-2023-54272"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54272"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.82-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1","6.1.55-1~bpo11+1","6.1.64-1","6.1.66-1","6.1.67-1","6.1.69-1","6.1.69-1~bpo11+1","6.1.76-1","6.1.76-1~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54272.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54272.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54272.json"}}],"schema_version":"1.9.0"}
