CVE-2026-98740

The Linux kernel contains a vulnerability where several a10 EDAC .setup callbacks (including sdmmc, ethernet, nand, dma, usb, and qspi) and their helpers were incorrectly marked with init . This allows for potential dereferencing of freed memory if a probe is deferred via -EPROBE_DEFER or trigge...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: Fix initial port reference race For RFCOMMRELEASEONHUP devices, rfcommttyinstall and rfcommreleasedev both use RFCOMMTTYOWNED to decide who drops the initial ttyport reference. The release path tests the bit...

CVE-2026-98739

A race condition exists in the Linux kernel Bluetooth RFCOMM stack, specifically affecting RFCOMM_RELEASE_ONHUP devices. The vulnerability occurs because rfcomm_tty_install() and __rfcomm_release_dev() independently check and set the RFCOMM_TTY_OWNED bit. This allows both paths to potentially dro...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Serialize SMP remote OOB data access buildpairingcmd looks up remote OOB data and copies its contents without holding hdev-lock, which serializes the list's writers. After SMP finds an entry, a concurrent management...

CVE-2026-98738

The Linux kernel contains a vulnerability in the Bluetooth stack where build_pairing_cmd() accesses remote OOB (Out-of-Band) data without holding the hdev->lock. This lack of synchronization allows a concurrent management command to unlink and free the data before the SMP (Security Manager Pro...

EUVD-2026-103822

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Fix inquiry cache use-after-free The sync command worker holds hdev-reqlock, but inquiry-cache updates and flushes use hdev-lock. Both hciaclcreateconnsync and hcistopdiscoverysync look up entries and read the...

CVE-2026-98737

A use-after-free vulnerability exists in the Linux kernel Bluetooth subsystem within hci_sync . The issue stems from a race condition where the sync command worker holds hdev->req_lock, while inquiry-cache updates and flushes utilize hdev->lock. Specifically, functions hci_acl_create_conn_s...

CVE-2026-98736

The Linux kernel contains a use-after-free vulnerability in the Bluetooth subsystem during enhanced SCO setup . The issue occurs because hci_enhanced_setup_sync() runs on the request workqueue without holding the hci_dev_lock . This allows the receive workqueue to unlink and release the ACL paren...
