Description
A flaw was found in the Linux kernel's Bluetooth bpa10x driver. This vulnerability allows a malicious Bluetooth device to trigger an out-of-bounds read in the bpa10x_setup() function by sending a specially crafted one-byte or non-NUL-terminated response. This can lead to information disclosure, where adjacent slab memory contents are written to the kernel log and firmware-info debugfs file.
