Transient service interruption via frame parser over-read
Published Feb 9, 2023 · Updated Aug 3, 2024
Buffer over-read in Qualcomm WLAN Host firmware allows remote attackers to transiently interrupt service via crafted frame information. The WLAN Host frame-information parser reads beyond a buffer boundary while decoding attacker-controlled frame metadata. Network access to an affected chipset is sufficient; the documented effect is transient denial of service, not data disclosure or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
