Subject: [PATCH] Fix potential use of uninitialized pipe array
|
|
|
|
We only call pipe(2) after the script is written to disk so if the
|
|
latter fails, the array will be left uninitialized and subsequently read
|
|
after skipping to the exit label. Fix by initializing it.
|
|
|
|
Found by Coverity.
|
|
|
|
Fixes: RHEL-22604
