Linux kernel smb_proc_readX_data denial of service

linux-smbprocreadxdata-dos (18135) The risk level is classified as LowLow Risk

Description:

Linux kernel is vulnerable to a denial of service attack, caused by a vulnerability in the smb_proc_readX_data function. A remote attacker, in control of a malicious SMB server, could send a specially-crafted packet to cause the kernel to crash.
