CVE-2025-37987: pds_core: Prevent possible adminq overflow/stuck condition

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2982e07ad72b48eb12c29a87a3f2126ea552688c, 517f928cc0c133472618cbba18382b46f5f71ba3, 5e3dc65675faad846420d24762e4faadc12d9392; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1.

Low priority for now. Upgrade to Linux Linux 2982e07ad72b48eb12c29a87a3f2126ea552688c, 517f928cc0c133472618cbba18382b46f5f71ba3, 5e3dc65675faad846420d24762e4faadc12d9392; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: pds_core: Prevent possible adminq overflow/stuck condition The pds_core's adminq is protected by the adminq_lock, which prevents more than 1 command to be posted onto it at any one time. This makes it so the client drivers cannot simultaneously post adminq commands. However, the completions happen in a different context, which means multiple adminq commands can be posted sequentially and all waiting on completion. On the FW side, the backing adminq request queue is only 16 entries long and the retry mechanism and/or overflow/stuck prevention is lacking. This can cause the adminq to get stuck, so commands are no longer processed and completions are no longer sent by the FW. As an initial fix, prevent more than 16 outstanding adminq commands so there's no way to cause the adminq from getting stuck. This works because the backing adminq request queue will never have more than 16 pending adminq commands, so it will never overflow. This is done by reducing the adminq depth to 16.
