A flaw out of bounds memory access in the Linux kernel bluetooth subsystem was found in the way when some data being read about the bluetooth device with the hci_extended_inquiry_result_evt call. A local user could use this flaw to crash the system or read some data out of memory bounds that can lead to data confidentiality threat.
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, double free, heap overflow, information leakage, null pointer, out of bounds read, and use-after-free vulnerabilities.
