The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: l2cap: Add missing chan lock in l2capecredreconfrsp l2capecredreconfrsp calls l2capchandel without holding l2capchanlock. Every other l2capchandel...

PT-2026-52349

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description RFCOMM MCC handlers cast skb-data to protocol-specific structs without first validating skb-len. This allows a malicious remote device to send truncated MCC frames, triggering...

PT-2026-52347

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the Bluetooth HCI UART configuration during early failures in the hci alloc dev function. When device initialization fails before hci register dev completes, the...

PT-2026-52371

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the Bluetooth ISO implementation. In the iso sock rebind bc function, the bis pointer is cached and the socket lock is subsequently dropped. A concurrent...

CVE-2026-53072

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix locking in hciconnrequestevt with HCIPROTODEFER When protocol sets HCIPROTODEFER, hciconnrequestevt calls hciconnectcfmconn without hdev-lock. Generally hciconnectcfm assumes it is held, and if conn is deleted...

CVE-2026-53073

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcildisc: Clear HCIUARTPROTOINIT on error When hciregisterdev fails in hciuartregisterdev HCIUARTPROTOINIT is not cleared before calling hu-proto-closehu and setting hu-hdev to NULL. This means incoming UART data will...
