ZDI-26-608: Linux Kernel KVM IOAPIC Use-After-Free Local Privilege Escalation Vulnerability

The Linux kernel KVM IOAPIC has a use-after-free (CVSS 8.2) allowing local privilege escalation, but exploitation requires high-privileged code execution first.

ZDI-26-608 describes a use-after-free vulnerability in the Linux kernel's KVM IOAPIC component, with a CVSS score of 8.2. An attacker must first obtain the ability to execute high-privileged code on the target system, which limits the practical impact of the privilege escalation. The advisory text does not list an assigned CVE identifier.

VU#859658: Skullcandy Dime 3 wireless earbuds contain an unauthenticated Bluetooth pairing vulnerability

Skullcandy Dime 3 earbuds (CVE-2025-20701) accept Bluetooth pairings without owner consent, letting in-range attackers hijack audio or capture microphone; no firmware update path exists.

CERT/CC's VU#859658 describes CVE-2025-20701 in the Airoha Bluetooth audio SDK, present in Skullcandy Dime 3 (Model S2DCW) firmware 1.0.0.28. A direct Bluetooth Classic pairing request with no PIN or physical confirmation completes via NoInputNoOutput, adding the attacker's device as trusted. Attackers in radio range can hijack the A2DP audio session, access the Hands-Free/Headset profile, and capture live microphone audio. Firmware 1.0.0.30 contains the effective patch, but Skullcandy says the Dime 3 does not support app-based firmware updates, leaving existing units unpatchable.
