CVE-2023-54300

A flaw was identified in the Linux kernel’s ath9k wireless driver where the receiver packet handling code did not correctly validate the length of incoming SKBs before accessing subsequent fields expected to be present. In certain malformed packet conditions (e.g., pkt_len set too small), the driver could reference uninitialized memory when attempting to parse expected control data, leading to unpredictable behavior including kernel warnings or crashes.
