Description
A flaw was found in the Linux kernel's wireless (iwlwifi) component. This vulnerability occurs when the system's wireless firmware encounters an error and is attempting to restart. During this critical period, an internal function, iwl_trans_reclaim, issues an unnecessary warning instead of silently recovering. This can lead to system instability, potentially causing a denial of service (DoS) where the system becomes unresponsive or crashes. A local attacker with low privileges could exploit this to impact system availability.
