Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ksmbd: fix a missing return value check bug<br /> <br /> In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct()<br /> fails to allocate a node, it returns a NULL pointer to the<br /> in_work pointer. This can lead to an illegal memory write of<br /> in_work-&gt;response_buf when allocate_interim_rsp_buf() attempts<br /> to perform a kzalloc() on it.<br /> <br /> To address this issue, incorporating a check for the return<br /> value of ksmbd_alloc_work_struct() ensures that the function<br /> returns immediately upon allocation failure, thereby preventing<br /> the aforementioned illegal memory access.
