Описание
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: pci: validate release report content before using for RTL8922DE
The commit 957eda596c76
("wifi: rtw89: pci: validate sequence number of TX release report")
does validation on existing chips, which somehow a release report of SKB
becomes malformed. As no clear cause found, add rules ahead for RTL8922DE
to avoid crash if it happens.
A flaw was found in the Linux kernel's rtw89 WiFi driver. This vulnerability arises from insufficient validation of release report content, specifically affecting the RTL8922DE chip. If a malformed release report is processed, it can lead to a system crash, resulting in a Denial of Service (DoS).
Отчет
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.
Меры по смягчению последствий
To mitigate this issue, prevent the rtw89 module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
