CVE-2024-45558

CVE-2024-45558 is a vulnerability in a Qualcomm driver that enables a transient denial-of-service (DoS) condition. It arises when the driver parses the per-station (STA) profile Information Element (IE) and attempts to access the EXTN element ID without first validating the IE length, resulting in a buffer over-read. This issue maps to CWE-126 (Buffer Over-read) and CWE-125 (Out-of-bounds Read), with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high-impact availability disruption without confidentiality or integrity effects.

A remote, unauthenticated attacker can exploit this vulnerability by crafting and transmitting a malicious per-STA profile IE to a vulnerable device. Successful exploitation triggers the unsafe access during IE parsing, causing a transient DoS that disrupts the affected driver's functionality, such as Wi-Fi connectivity, without requiring user interaction or privileges.
