CyberRota Analysis
AI-GeneratedA critical vulnerability in the Linux kernel affects the SMB client, where a double-free condition can occur during directory query operations due to improper handling of response buffers. This flaw could lead to potential denial-of-service attacks or arbitrary code execution, making it essential for organizations using Linux systems, particularly those relying on SMB for file sharing, to prioritize patching. Immediate action is recommended for system administrators and security teams to mitigate risks associated with this vulnerability.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix query directory replay double-free A response-bearing attempt can return a replayable error and free its response buffer. If SMB2_query_directory_init() fails before the next send, cleanup retains the previous buffer type and frees that response again. Reset response bookkeeping before each attempt to prevent the stale free.
