Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

There is a known vulnerability in the l2capparseconfreq function of the Linux kernel’s net/bluetooth/l2capcore.c file, which can be exploited to remotely leak kernel pointers. We recommend upgrading to a later commit:...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed a division by zero issue in l2capleflowctlinit. l2capleflowctlinit may cause both a division by zero and an integer overflow, as hdev-lemtu may not fall within the valid range. The MTU value was moved...

CVE-2026-74540

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol component. A use-after-free UAF vulnerability exists in the l2capleconnectrsp function, where a channel can be freed while still being referenced. This can be triggered by a remote disconnect,...

CVE-2026-74507

A flaw was found in the Linux kernel's Bluetooth Human Interface Device Protocol HIDP component. A connected HIDP peer can send a malformed report with only a data transaction header, leading to the use of an uninitialized value in hidpsessionrun. This vulnerability could potentially result in a...

CVE-2026-18281

CVE-2026-18281 is a heap-based buffer overflow in the Sony XAV-9500ES car audio/video receiver, specifically in the l2_reassemble_sdu function that handles Bluetooth L2CAP packets . The root cause is the lack of proper length validation on user-supplied data before copying it into a heap-based bu...

CVE-2026-18278

The Sony XAV-9500ES infotainment system's prh_l2_decode_packet function lacks proper validation of Bluetooth L2CAP packet data, causing an out-of-bounds buffer read. Attackers must first pair a malicious Bluetooth device, then can disclose sensitive information; chaining with other flaws may enab...

CVE-2026-72336

A flaw was found in the Linux kernel's Bluetooth 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks component. A race condition exists where an L2CAP Logical Link Control and Adaptation Protocol connection is accessed after its protection is dropped, allowing it to be deallocated...

CVE-2026-72333

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol implementation. A remote attacker, by continuously streaming data to a host, can trigger an identifier ident leak. This occurs because identifiers for certain commands, such as L2CAPLECREDITS, are...

The vulnerability in the `net/bluetooth/l2cap_core.c` component of the Linux operating system allows a hacker to gain access to confidential data and compromise its integrity.

The vulnerability of the net/bluetooth/l2capcore.c component in the Linux operating system is related to incorrect checking of the data size at the input stage. Exploiting this vulnerability can allow an attacker to gain access to confidential data and compromise its integrity...
