- Summary
- block: fix memory leak in __blkdev_issue_zero_pages
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
block: fix memory leak in _blkdevissuezeropages
Move the fatal signal check before bioalloc() to prevent a memory leak when BLKDEVZERO_KILLABLE is set and a fatal signal is pending.
Previously, the bio was allocated before checking for a fatal signal. If a signal was pending, the code would break out of the loop without freeing or chaining the just-allocated bio, causing a memory leak.
This matches the pattern already used in _blkdevissuewritezeroes() where the signal check precedes the allocation.
