  "title": "ksmbd: fix buffer validation by including null terminator size in EA length",
  "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 (\u002B1 byte) for EA Name. This patch fixes the issue by explicitly adding \u0027\u002B 1\u0027 to EaNameLength where the null terminator is expected to be present in the buffer, ensuring the validation accurately reflects the total required buffer size.",
