MEDIUM 5.5

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy()

We can't call destroy_workqueue(smb_direct_wq); before stop_sessions()!

Otherwise already existing connections try to use smb_direct_wq as a NULL pointer.

AnalysisAI

In the Linux kernel, the following vulnerability has been resolved: smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy() We can't call destroy_workqueue(smb_direct_wq); before. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.

Technical ContextAI

This vulnerability is classified as NULL Pointer Dereference (CWE-476), which allows attackers to crash the application by dereferencing a null pointer. In the Linux kernel, the following vulnerability has been resolved: smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy() We can't call destroy_workqueue(smb_direct_wq); before stop_sessions()! Otherwise already existing connections try to use smb_direct_wq as a NULL pointer. Affected products include: Linux Linux Kernel, Debian Debian Linux.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Check pointers before dereferencing. Use static analysis tools to detect null pointer paths.
