Описание
In the Linux kernel, the following vulnerability has been resolved:
wifi: wlcore: Fix a locking bug
Make sure that wl->mutex is locked before it is unlocked. This has been
detected by the Clang thread-safety analyzer.
A flaw was found in the Linux kernel's wlcore Wi-Fi driver. This vulnerability involves an improper handling of a locking mechanism, specifically the wl->mutex. This can lead to system instability or unexpected behavior. The issue was identified by a thread-safety analyzer.
Отчет
This affects systems using the wlcore stack (for example TI WiLink). Wireless drivers sit on the networking boundary; locking defects deserve conservative triage even when exploitation is uncertain. Impact is mainly reliability and possible local denial of service if the bad path is hit.
Меры по смягчению последствий
To mitigate this issue, prevent the wlcore or device-specific wlan module from being loaded if the hardware is not required. See https://access.redhat.com/solutions/41278 for instructions.
