GHSA-45gw-fx24-h4pv PUBLISHED CVSS 7.800000190734863 HIGH

Record from GitHub Advisory Database · Published May 1, 2025

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix dangling pointer in krb_authenticate krb_authenticate frees sess->user and does not set the pointer to NULL. It calls ksmbd_krb5_authenticate to reinitialise sess->user but that function may return without doing so. If that happens then smb2_sess_setup, which calls krb_authenticate, will be accessing free'd memory when it later uses sess->user.
