CVE-2026-46327

In the Linux kernel dm subsystem, the vulnerability centers on dm_blk_report_zones checking for suspended state without holding locks, allowing a race where the device may be suspended immediately after the check. The fix moves the dm_suspended_md check to occur after dm_get_live_table, ensuring ...

CVE-2026-46327 dm: fix unlocked test for dm_suspended_md

In the Linux kernel, the following vulnerability has been resolved: dm: fix unlocked test for dmsuspendedmd The function dmblkreportzones tests if the device is suspended with the "dmsuspendedmd" call. However, this function is called without holding any locks, so the device may be suspended just...
