CVE-2026-68189
A flaw was found in the Bluetooth hcisync component of the Linux kernel. A race condition during the UUID list traversal, caused by improper synchronization between asynchronous command sync work and UUID list updates, can lead to a use-after-free vulnerability. This could allow a local attacker ...
CVE-2026-68390
A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hcisync component. This vulnerability occurs because the hciconnparamslookup function does not properly hold a necessary lock hdev-lock during operations. This oversight can lead to unsafe list iterations or...
