CVE-2026-46111

The CVE concerns a use-after-free in the Linux kernel Bluetooth stack (hci_conn, BIG creation). The patch adds hci_conn_valid() in create_big_sync() to detect stale connections before BIG creation, handles -ECANCELED in create_big_complete(), and re-validates under hci_dev_lock() before dereferen...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the potential for reusing memory after the creation of the createbigsync function in the Bluetooth HCI...

kernel: Bluetooth: Ignore too large handle values in BIG

A vulnerability was found in the Linux kernel's bluetooth subsystem in the function hcilebigsyncestablishedevt where a lack of proper checks does not validate whether a received connection handle exceeds the maximum allowed value. This could lead to system instability or crashes...

kernel: bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX

A warning was observed in the Linux kernel in hciconndel caused by freeing handle that was not allocated using ida allocator. This is caused by handle bigger than HCICONNHANDLEMAX passed by hcilebigsyncestablishedevt, which makes code think it's unset connection...
