CVE-2026-98294

The Linux kernel contains a vulnerability in the hci_qca driver where the system attempts to write to a serial port after it has been closed. Specifically, if HCI_QUIRK_NON_PERSISTENT_SETUP is set (e.g., for the WCN399x family), a failed hci_dev_open_sync() after a successful qca_setup() leads to...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix parent socket leak in isoconnready isogetsock returns the parent socket with a reference held, which is dropped by sockput once the child socket has been set up. The error path taken when isosockalloc fails on...

CVE-2026-98293

The Linux kernel contains a memory leak vulnerability within the Bluetooth ISO component. Specifically, the iso_conn_ready() function fails to properly release a reference to the parent socket when iso_sock_alloc() fails. While the reference is normally dropped by sock_put() upon successful child...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtksdio, btmtkuart: validate WMT event length before struct access btmtksdio.c and btmtkuart.c cast a received WMT event straight to struct btmtkhciwmtevt and read its op/flag fields without checking the event is lon...

CVE-2026-98292

The Linux kernel contains a vulnerability in the btmtksdio and btmtkuart Bluetooth drivers. The issue arises because these drivers cast received WMT events directly to struct btmtk_hci_wmt_evt and read fields without verifying the event length. Additionally, in the FUNC_CTRL case, the drivers cas...
