TIMELINE Apr 16 Reserved by Linux May 1 Published (CNA: Linux) Aug 4 RESCORED — CVE-2025-37778 (Linux). CVSS 9.8 → 7.8 (NVD).
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.
