Description
A bounds off-by-one vulnerability in the Linux kernel Bluetooth driver btintel_pcie was fixed. The issue involved an incorrect boundary check on tx_handle indices, which could lead to out-of-range access. The fix changes the guard condition to prevent accessing invalid indices. This vulnerability affects Linux kernel version 6.10 and has been resolved in subsequent commits.
