https://notcve.org/view.php?id=CVE-2025-38066
18 Jun 2025 — In the Linux kernel, the following vulnerability has been resolved: dm cache: prevent BUG_ON by blocking retries on failed device resumes A cache device failing to resume due to mapping errors should not be retried, as the failure leaves a partially initialized policy object. Repeating the resume operation risks triggering BUG_ON when reloading cache mappings into the incomplete policy object. Reproduce steps: 1. create a cache metadata consisting of 512 or more cache blocks, with some mappings stored in th... • https://git.kernel.org/stable/c/c614584c2a66b538f469089ac089457a34590c14 •
