      SELinux: Fix RCU deref check warning in sel_netport_insert() · 94d4ef0c
      David Howells 提交于
      Fix the following bug in sel_netport_insert() where rcu_dereference() should
      be rcu_dereference_protected() as sel_netport_lock is held.
      
      ===================================================

      crypto: ghash - Avoid null pointer dereference if no key is set · 7ed47b7d
      Nick Bowler 提交于
      The ghash_update function passes a pointer to gf128mul_4k_lle which will
      be NULL if ghash_setkey is not called or if the most recent call to
      ghash_setkey failed to allocate memory.  This causes an oops.  Fix this
      up by returning an error code in the null case.
      
      This is trivially triggered from unprivileged userspace through the
      AF_ALG interface by simply writing to the socket without setting a key.
      
      The ghash_final function has a similar issue, but triggering it requires
      a memory allocation failure in ghash_setkey _after_ at least one
      successful call to ghash_update.
