CVSS: 9.0EPSS: 0%CPEs: 9EXPL: 0CVE-2023-32250 – Session race condition remote code execution vulnerability
https://notcve.org/view.php?id=CVE-2023-32250
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. • https://access.redhat.com/security/cve/CVE-2023-32250 https://bugzilla.redhat.com/show_bug.cgi?id=2208849 https://security.netapp.com/advisory/ntap-20230824-0004 https://www.zerodayinitiative.com/advisories/ZDI-23-698 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
