8.5

High

VectorAV:N/AC:L/Au:S/C:C/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An out-of-bounds (OOB) memory read flaw was found in the parse lease state() function in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of NameOffset in the parse lease state() function, the create context object can access invalid memory. This issue is related to errors in variable initialization in the parse lease state() function. Exploitation of this issue may allow an attacker to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
