Found In Version: 10.23.30.2
Severity: Standard
Applicable for: Wind River Linux LTS 23
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: fix buffer validation by including null terminator size in EA length

The smb2_set_ea function, which handles Extended Attributes (EA),
was performing buffer validation checks that incorrectly omitted the size
of the null terminating character (+1 byte) for EA Name.
This patch fixes the issue by explicitly adding '+ 1' to EaNameLength where
the null terminator is expected to be present in the buffer, ensuring
the validation accurately reflects the total required buffer size.
