In the Linux kernel, the following vulnerability has been resolved:
selinux: fix double free of cond_list on error paths
On error path from cond_read_list() and duplicate_policydb_cond_list()
the cond_list_destroy() gets called a second time in caller functions,
resulting in NULL pointer deref. Fix this by resetting the
cond_list_len to 0 in cond_list_destroy(), making subsequent calls a
noop.
Also consistently reset the cond_list pointer to NULL after freeing.
