In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed a use-after-free in l2capdisconnectreq,rsp. Similar to the issue reported in commit d0be8347c623 "Bluetooth: L2CAP: Fix use-after-free caused by l2capchanput", use l2capchanholdunlesszero to prevent...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed a use-after-free caused by l2capreassemblesdu. Fixed a race condition between the following two processes that run parallelly: 1. l2capreassemblesdu - chan-ops-recv l2capsockrecvcb - sockqueuercvskb. 2...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: fixed the “bad unlock balance” issue in l2capdisconnectrsp. The conn-chanlock is not acquired before l2capgetchanbyscid. If l2capgetchanbyscid returns NULL, then the “bad unlock balance” issue will be trigger...

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed an issue where user input was not validated. The length of user input was checked before data was copied...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fixed a potential issue after the “user-after-free” operation. This fix addresses all cases where allocating a buffer using allocskb might release the “chan lock”, and reacquiring it later could result in the...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fix for u8 overflow By continuously sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times, eventually exceeding the maximum number i.e., 255. This patch prevents this issue by adding a bounda...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix use-after-free in l2capsocknewconnectioncb l2capsocknewconnectioncb returned l2cappisk-chan after releasesockparent. Once the parent lock is dropped the newly enqueued child socket sk is reachable via the...

CVE-2026-64408

A flaw was found in the Bluetooth Network Encapsulation Protocol BNEP module of the Linux kernel. The bnepaddconnection function reads the Logical Link Control and Adaptation Protocol L2CAP connection without properly holding a channel lock. This can allow a local attacker to trigger a...

CVE-2026-64557

A flaw was found in the Linux kernel's Bluetooth L2CAP component. A race condition exists during the handling of new Bluetooth connections, where a newly created socket can be prematurely freed by another process before a callback function completes its operation. This use-after-free vulnerabilit...

CVE-2026-64403

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. The l2capgetconfopt function, responsible for processing configuration options, does not properly validate the length of an option before attempting to read its value. This allows a...
