Title
ksmbd: fix buffer validation by including null terminator size in EA length
Summary
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.
Severity ?
No CVSS data available.
