CVE-2026-43488

A flaw was found in the Linux kernel's xHCI eXtensible Host Controller Interface driver. When a USB Attached SCSI UAS storage device is connected or disconnected, the xHCI controller can report a Host Controller Error HCE. Improper handling of this error can lead to an interrupt storm, causing...

SUSE CVE-2026-43353

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Fix race in DMA ring dequeue The HCI DMA dequeue path hcidmadequeuexfer may be invoked for multiple transfers that timeout around the same time. However, the function is not serialized and can race with itself...

CVE-2026-43352

A flaw was found in the Linux kernel's I3C Improved Inter-Integrated Circuit Host Controller Interface HCI driver. Incorrect handling of DMA Direct Memory Access ring aborts can lead to the unintentional clearing of RINGCTRLENABLE. This action resets hardware ring pointers and disrupts the...

CVE-2026-43322

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Fix UAF in lereadfeaturescomplete This fixes the following backtrace caused by hciconn being freed before lereadfeaturescomplete but after hcilereadremotefeaturessync so hciconndel - hcicmdsyncdequeue is not...

PT-2026-39014

SUSE CVE-2026-43022

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hcicmdsyncqueueonce return -EEXIST if exists hcicmdsyncqueueonce needs to indicate whether a queue item was added, so caller can know if callbacks are called, so it can avoid leaking resources. Change the...

SUSE CVE-2026-43023

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: SCO: fix race conditions in scosockconnect scosockconnect checks skstate and sktype without holding the socket lock. Two concurrent connect syscalls on the same socket can both pass the check and enter scoconnect,...

PT-2026-37429

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A data race exists in the Bluetooth component involving the hdev-req status variable. While hci cmd sync sk modifies this variable under the hdev-req lock, other functions—including hci...

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...
