Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Affected versions of this package are vulnerable to Use After Free in the handler for the SMB ‘logoff’ command due to the sess->user
object that can currently be in use by another thread. For example if another connection has sent a session setup request to bind to the session being freed, the handler for that connection could be in the smb2_sess_setup
function which makes use of sess->user
. Depending on the exact timing, an attacker could cause either a use‑after‑free or a NULL pointer dereference, both leading to denial of service.
