In the Linux kernel, the following vulnerability has been resolved: block: fix memory leak in __blkdev_issue_zero_pages Move the fatal signal check before bio_alloc() to prevent a memory leak when BLKDEV_ZERO_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 __blkdev_issue_write_zeroes() where the signal check precedes the allocation.
Conclusion & alert: CVE-2025-68348 is rated Low Risk (6.6/100): low exploitation likelihood (EPSS 0.17%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
