- Details
-
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.
[PM: fix line lengths in the description]
