Information disclosure via L2CAP packet out-of-bounds read
Published Aug 20, 2026 · Updated Aug 20, 2026
Out-of-bounds read in Sony XAV-9500ES 3.02.0.0 allows network-adjacent attackers to disclose memory contents via crafted Bluetooth packets. Within prh_l2_decode_packet, Bluetooth L2CAP packet data is not validated before buffer reads, allowing reads past the end of an allocated buffer. Exploitation requires pairing a malicious Bluetooth device with the receiver; published records describe confidentiality impact, with code execution only when combined with other vulnerabilities.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
