CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's Bluetooth implementation, specifically in the handling of LE Set CIG Parameters responses. An attacker could exploit this flaw by sending a malformed response, potentially leading to out-of-bounds memory reads and instability in Bluetooth communications. Organizations utilizing Linux systems with Bluetooth capabilities should prioritize addressing this issue to mitigate potential exploitation risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: validate LE Set CIG Parameters response The Command Complete dispatch validates only the fixed part of the LE Set CIG Parameters response. After that part is pulled from the skb, hci_cc_le_set_cig_params() trusts num_handles and reads each entry in the trailing handle array. Matching num_handles against the command's num_cis does not guarantee that the response contains the advertised handles. A truncated response from a malfunctioning controller can therefore make the handler read beyond the skb data. Validate that the remaining skb data contains all advertised handles. Include this in the existing response validation so malformed responses also follow the established CIG failure handling.
