CVE-2026-80721

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream implementation. This vulnerability occurs because the system does not properly clear references to connection handles hcon after a connection is deleted. This oversight can lead to unpredictable system behavior or instability...

SUSE CVE-2026-80721

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: ensure no dangling hcon references in isoconn After isoconndel, ISO sockets should not dereference the hcon any more. Currently, clearing isoconn::hcon relies on isoconndel releasing the last reference to the...

CVE-2026-80721

A dangling pointer vulnerability exists in the Linux kernel Bluetooth ISO (Isochronous) subsystem. After iso_conn_del() is called, ISO sockets may still dereference the hcon (HCI connection) pointer because clearing iso_conn::hcon previously relied on iso_conn_del() releasing the last reference t...

PT-2026-83021

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Bluetooth ISO implementation where ISO sockets may dereference the hcon reference after the iso conn del function has been called. This occurs because the clearing...

CVE-2026-74541

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability arises from the system's failure to properly clear isodata when a connection is detached from its host controller connection hcon. A local attacker could exploit this use-after-free condition to cause a denial of...

CVE-2026-74541

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: clear isodata always when detaching conn from hcon When setting conn-hcon = NULL, also conn-hcon-isodata = NULL is necessary, otherwise later isoconnfree will UAF. Fix clearing of isodata in isosockdisconn Fixes...

kernel: Bluetooth: Fix use after free in hci_send_acl

A vulnerability was found in the Linux kernel's Bluetooth subsystem in the hcidisconnphylinkcompleteevt function. Improper cleanup and reference handling can lead to a connection object, hcon, being freed and then later accessed during a subsequent function call. This issue can lead to a...
