CVE-2026-74531

CVE-2026-74531 affects the Linux kernel Bluetooth implementation, specifically the hci_conn path used by abort_conn_sync. The root cause is a potential use-after-free if the connection object is freed while the hci_sync task is running. The documented fix is to hold a reference (refcount) to the ...

CVE-2026-74529

In the Linux kernel Bluetooth subsystem, the issue is in the hci_sync path: the conn object could be freed while the hci_sync task is running in hci_connect_pa_sync(), creating a theoretical use-after-free. The documented fix is to hold a refcount on the conn to prevent deallocation during the ca...

CVE-2026-74528

The CVE refers to the Linux kernel Bluetooth subsystem: hci_sync in the hci_past_sync() callback, which previously could dereference freed pointers to hci_conn_valid() due to kmalloc reuse. The fix holds a reference count on the connection to ensure resources remain valid, preventing use-after-fr...
