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...

CVE-2026-31771

A flaw was found in the Linux kernel's Bluetooth subsystem. A remote attacker could exploit a missing bounds check by sending a specially crafted, short Bluetooth Host Controller Interface HCI event frame. This could lead to a buffer overflow, potentially allowing the attacker to cause a denial o...

CVE-2026-43018

A flaw was found in the Linux kernel's Bluetooth component. This Use-After-Free UAF vulnerability arises from insufficient locking during hciconn lookup and access within the hcileremoteconnparamreqevt function. An attacker could potentially exploit this to cause a system crash or execute arbitra...

EUVD-2026-24876

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: serialize btintelhwerror with hcireqsynclock btintelhwerror issues two hcicmdsync calls HCIOPRESET and Intel exception-info retrieval without holding hcireqsynclock. This lets it race against hcidevdoclose -...

PT-2026-34405

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the Bluetooth component where the btintel hw error function issues synchronous HCI commands without holding the hci req sync lock lock. This allows it to race...
