USN-8296-1: Linux kernel (FIPS) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Compute Acceleration Framework; - Drivers core; - Null block device drive...

OESA-2026-2419 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Validate L2CAPINFORSP payload length before access l2capinformationrsp checks that cmdlen covers the fixed l2capinforsp header type + result, 4...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: Memory allocation for driver-private data was not performed. The issue was that the driver did not allocate memory for the struct btinteldata structure, which is used to store internal data...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: lookup hciconn on the RX path at the protocol level The hdev lock/lookup/unlock/use pattern in the packet RX path does not ensure that hciconn is not concurrently modified/deleted. This locking mechanism seems...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: Fixed an issue involving a use-after-free in hcisendacl. This fix addresses the issue caused by receiving HCIEVDISCONNPHYLINKCOMPLETE, which does not call hciconndel without first checking whether conn-type is indee...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Potential use-after-free issues have been avoided in hcierrorreset. When handling the HCIEVHARDWAREERROR event, if the underlying BT controller is not responding, the GPIO reset mechanism will free the hcidev, leading ...

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: Avoid using hcidevtestandsetflag in mgmtinithdev. syzbot is once again reporting attempts to cancel uninitialized operations at mgmtindexremoved. The sequence of operations—setting the HCIMGMT flag from mgmtinithdev...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed a deadlock in l2capconndel. The l2capconndel function calls canceldelayedworksync for both infotimer and idaddrtimer while holding conn-lock. However, the functions l2capinfotimeout and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Purge error queues in socket destructors When TX timestamping is enabled via SOTIMESTAMPING, SKBs may be queued into skerrorqueue and will remain there until they are consumed. If userspace never gets to read the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hciconn: fails to handle SCO/ISO via hciconnfailed if the ACL is deleted prematurely. Not calling hcidisconnectcfm before deleting a connection referenced by a socket generally results in a “use-after-free” issue...
