CVE-2024-36033: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-36033 is a vulnerability in the Linux kernel's Bluetooth QCA driver that was discovered and disclosed in May 2024. The vulnerability specifically affects the board ID fetching functionality in the Bluetooth QCA driver, which could potentially leak slab data when requesting firmware (Kernel Git).

The vulnerability stems from a missing sanity check when fetching the board ID in the Linux kernel's Bluetooth QCA driver. The issue occurs in the qca_read_fw_board_id function where there was no validation of the data length before accessing it, potentially leading to slab data leakage during firmware requests. The fix involves adding a length check to ensure the received data buffer contains at least 3 bytes before accessing the board ID information (Kernel Git).

The vulnerability could lead to information disclosure through slab data leakage when requesting firmware for QCA Bluetooth devices. This could potentially expose sensitive kernel memory contents to unauthorized users (Kernel Git).

The vulnerability has been patched in the Linux kernel with a fix that adds proper sanity checks when fetching the board ID. The patch has been backported to multiple stable kernel versions. Users should update their Linux kernel to a version that includes this security fix (Kernel Git).
