CVE-2025-37778CVE-2025-37778
linux / linux_kernel
Description
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.
