# CVE-2024-50147: linux: In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix command bitmask initialization Co... CVE-2024-50147 is fixed in 47 products on 1 platform, first by DEBIAN-CVE-2024-50147, released November 7, 2024. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2024-50147 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0023 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Nov 7, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix command bitmask initialization Command bitmask have a dedicated bit for MANAGE_PAGES command, this bit isn't Initialize during command bitmask Initialization, only during MANAGE_PAGES. In addition, mlx5_cmd_trigger_completions() is trying to trigger completion for MANAGE_PAGES command as well. Hence, in case health error occurred before any MANAGE_PAGES command have been invoke (for example, during mlx5_enable_hca()), mlx5_cmd_trigger_completions() will try to trigger completion for MANAGE_PAGES command, which will result in null-ptr-deref error.[1] Fix it by Initialize command bitmask correctly. While at it, re-write the code for better understanding.
