CVE-2024-53156

Summary

CVE-2024-53156 is a newly discovered vulnerability in the Linux kernel's ath9k driver. A bug was identified in the htc_hst.c file, where an out-of-bounds array index was being accessed. Specifically, the index 255 was found to be out of range for the htc_endpoint type, causing UBSAN (Uninitialized Value Safety Analysis) to trigger. This vulnerability, if exploited, could lead to undefined behavior. To prevent such occurrences, it is recommended to add a range check for conn_rsp_epid in the htc_connect_service() function. This update will ensure that array indices remain within their defined boundaries, thereby mitigating the risk associated with this vulnerability.
