CVE-2025-38496

CVE-2025-38496 concerns the Linux kernel and relates to the dm-bufio component. The issue occurs when the DM_BUFIO client is configured with NO_SLEEP and verity integration, where buffer eviction could trigger scheduling in spin_lock_bh, potentially leading to a sleeping operation in an atomic co...
