https://notcve.org/view.php?id=CVE-2023-32252
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_LOGOFF commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. • https://access.redhat.com/security/cve/CVE-2023-32252 https://bugzilla.redhat.com/show_bug.cgi?id=2219815 https://security.netapp.com/advisory/ntap-20231124-0001 https://www.zerodayinitiative.com/advisories/ZDI-CAN-20590 • CWE-476: NULL Pointer Dereference •
