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.

Affected configurations

• linux linux kernel (>= 5.15 < 6.1.135) • linux linux kernel (>= 6.2 < 6.6.88) • linux linux kernel (>= 6.7 < 6.12.25) • linux linux kernel (>= 6.13 < 6.14.4) • linux linux kernel 6.15 • debian debian linux 11.0
