CVE-2022-49326 is a kernel panic vulnerability in the Linux kernel's rtl818x wireless driver, specifically affecting rtl8180/rtl8185 cards. This medium-severity vulnerability (CVSS 5.5) can be triggered by a local attacker with low privileges, leading to a denial of service (system crash). The issue arises from the driver attempting to use uninitialized transmit queues when wpa_supplicant 2.10 or later tries to set a priority for these cards, which lack Quality of Service (QoS) support. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
