CVE-2022-49238

A vulnerability was found in the Linux kernel's ath11k driver, where an accidental skip was introduced during peer deletion, originally intended to fix a firmware crash by changing the WMI command sequence. This results in a potential use-after-free scenario caused by the peer structure not being set to NULL and thus being accessed later on by other functions. This issue can lead to memory corruption, system instability, and potential code execution.

This vulnerability is rated as Moderate impact because exploitation requires the presence of specific Qualcomm wireless hardware (such as QCA6390 or WCN6855) and an active station connection being terminated. Typical Red Hat Enterprise Linux enterprise deployments run on server hardware lacking these Wi-Fi chipsets, substantially limiting exposure. While a local or adjacent actor could trigger the use-after-free condition during access point disconnection to crash the system or corrupt memory, the specialized hardware requirement prevents broad applicability.
