CVE-2025-71273

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. This vulnerability is caused by a memory leak within the rtw_register_hw() function, where memory allocated for supported bands is not properly released during error conditions. This could allow a local attacker to exhaust system memory, leading to a denial of service (DoS).

Red Hat acknowledges the upstream Linux kernel correction for «wifi» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the rtw88 module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
