Technical details
A race condition was identified in the net/bluetooth component of the Linux kernel, specifically within the sniff_min_interval_set() and sniff_max_interval_set() functions. The vulnerability stems from improper synchronization during concurrent execution when setting Bluetooth sniff intervals. An attacker with high privileges and adjacent network access could exploit this race condition to trigger a 'sniffing exception,' leading to a denial of service (DoS). The issue affects kernel versions up to 3.19.8 and the 6.x branch up to 6.7.2. Siemens has also confirmed impact on the GNU/Linux subsystem of SIMATIC S7-1500 TM MFP devices.
