CVE-2026-46327 is fixed in 58 products on 1 platform, first by ALAS2023-2026-1514, released March 30, 2026. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2026-46327 - Priority: High - CVSS: 7.8 (high) - EPSS: 0.0010 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Mar 30, 2026 ## Description In the Linux kernel, the following vulnerability has been resolved: dm: fix unlocked test for dm_suspended_md The function dm_blk_report_zones tests if the device is suspended with the "dm_suspended_md" call. However, this function is called without holding any locks, so the device may be suspended just after it. Move the call to dm_suspended_md after dm_get_live_table, so that the device can't be suspended after the suspended state was tested. ## Where it's fixed | Platform | Product | Fixed in | Fix |
