It was discovered that the BigBen Interactive Kids' gamepad driver in the Linux kernel did not properly handle device removal, leading to a use- after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-25012)

It was discovered that a race condition existed in the TLS subsystem in the Linux kernel, leading to a use-after-free or a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-28466)

It was discovered that the Bluetooth subsystem in the Linux kernel did not properly initialize some data structures, leading to an out-of-bounds access vulnerability in certain situations. An attacker could use this to expose sensitive information (kernel memory). (CVE-2023-28866)
