{"id":"DEBIAN-CVE-2024-44992","details":"In the Linux kernel, the following vulnerability has been resolved:  smb/client: avoid possible NULL dereference in cifs_free_subrequest()  Clang static checker (scan-build) warning: \tcifsglob.h:line 890, column 3 \tAccess to field 'ops' results in a dereference of a null pointer.  Commit 519be989717c (\"cifs: Add a tracepoint to track credits involved in R/W requests\") adds a check for 'rdata-\u003eserver', and let clang throw this warning about NULL dereference.  When 'rdata-\u003ecredits.value != 0 && rdata-\u003eserver == NULL' happens, add_credits_and_wake_if() will call rdata-\u003eserver-\u003eops-\u003eadd_credits(). This will cause NULL dereference problem. Add a check for 'rdata-\u003eserver' to avoid NULL dereference.","modified":"2026-09-15T09:03:03.685520995Z","published":"2024-09-04T20:15:08.207Z","upstream":["CVE-2024-44992"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-44992"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.10.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-44992.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.10.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-44992.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
