CVE-2026-74717
7.5 · HIGHOverview
CVE-2026-74717 is a high-severity vulnerability. It was published on August 22, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: fw_tracer, return NULL on create error
Tracer creation can fail by returning either NULL or ERR_PTR.
The return value is stored without a check on the device, and users
treat ERR_PTR and NULL the same way.
This also causes a crash in the core dump logic, which is missing the
ERR_PTR check and ends up dereferencing it, as shown in the trace below.
Switch tracer creation to return NULL on failure only, so callers only
need a single NULL check.
