Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
The issue is related to a buffer overflow in the SMB2 IOCTL request handling. When using encryption, the client will squash all compound request buffers down for encryption into a single iov in
smb2 set next command(). If the user passes an input buffer that is greater than 328 bytes, smb2 set next command() will end up writing off the end of @rqst->iov[0].iov base. This can be triggered by creating a symbolic link with a long name on a mounted CIFS share with the seal option.Recommendations:
To resolve the issue, update the Linux kernel to version 6.6.61 or later. As a temporary workaround, consider avoiding the use of the
seal mount option for CIFS shares until the update is applied. Additionally, restrict access to the vulnerable smb2 set next command() function and related API endpoints, such as /mnt/link, to minimize the risk of exploitation.قابلية الاستغلال
