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...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: ISO: Fixed issues related to locking and validity checks for isoconn. sk-skstate indicates whether isopisk-conn is valid. Operations that check or update skstate and access conn should hold locksock; otherwise, they...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: ISO: Fixed UAF in isosocktimeout The conn-sk might have been unlinked/freed while waiting for isoconnlock. Therefore, this check determines whether conn-sk is still valid by verifying that it is part of isosklist...

CVE-2026-74534

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. A race condition between isoconndel and isochandel functions can lead to a double-put of isoconn objects. This can result in a Use-After-Free UAF vulnerability, potentially allowing an attacker to cause a denial of service or achieve...

CVE-2026-74533

A flaw was found in the Bluetooth ISO subsystem of the Linux kernel. This vulnerability is caused by a race condition where certain data is accessed and modified without proper synchronization, leading to a use-after-free UAF error. An attacker could potentially exploit this to execute arbitrary...

CVE-2026-74537

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. A race condition in the isoconnready function allows a socket to be prematurely freed while still in use. This Use-After-Free UAF vulnerability could lead to memory corruption, potentially causing a system crash or other unpredictabl...

CVE-2026-74539

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. A missing lock in a critical function allows for concurrent access to internal data structures without proper synchronization. This concurrency issue could lead to system instability or a denial of service, impacting the availability...

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-2026-74536

A flaw was found in the Bluetooth ISO subsystem of the Linux kernel. This vulnerability occurs due to an issue in how socket references are managed after a socket is released, specifically within the isosockkill and isosockclose functions. This improper handling leads to a memory leak, which a...

CVE-2026-74535

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability arises from a race condition where the isosocktimeout function can execute concurrently with isoconndel, leading to a Use-After-Free UAF condition. A UAF vulnerability allows an attacker to potentially execute...

CVE-2026-72334

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream handling. A remote attacker, by sending specially crafted malformed Bluetooth ISO packets, could trigger a kernel panic, leading to a denial of service. Additionally, this vulnerability could result in a memory leak within th...

CVE-2026-74538

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A missing lock when accessing socket connection information within the isoconnectind function could lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash,...

SUSE CVE-2026-74535

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: avoid deadlocks in isosocktimeout isosocktimeout takes locksock, so sync disabling the timer while holding that lock may deadlock. isosocktimeout may also run concurrently with isoconndel, which leads to UAF Task ...
