In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Fix dangling pointer in krb_authenticate
krbauthenticate frees sess->user and does not set the pointer to NULL. It calls ksmbdkrb5authenticate to reinitialise sess->user but that function may return without doing so. If that happens then smb2sesssetup, which calls krbauthenticate, will be accessing free'd memory when it later uses sess->user.
