Details

In the Linux kernel, the following vulnerability has been resolved: selinux: fix double free of condlist on error paths On error path from condreadlist() and duplicatepolicydbcondlist() the condlistdestroy() gets called a second time in caller functions, resulting in NULL pointer deref. Fix this by resetting the condlistlen to 0 in condlistdestroy(), making subsequent calls a noop. Also consistently reset the cond_list pointer to NULL after freeing. [PM: fix line lengths in the description]
