PatchTheCVECVE-2024-26889: In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix possible buffer
CVE-2024-26889 is a medium-severity flaw (CVSS 5.5) affecting linux kernel, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix possible buffer overflow struct hci_dev_info has a fixed size name[8] field so in the event that hdev->name is bigger than that strcpy would attempt to write past its size, so this fixes this problem by switching to use strscpy.
