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...

CVE-2026-43275

In the Linux kernel, a race condition in the UFS core driver can occur during system suspend when Runtime Power Management (RPM) level is zero. The driver previously bypassed flushing the exception-event handling work in this state, risking illegal host-controller access after entering deep power...

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

Linux Distros Unpatched Vulnerability : CVE-2026-31754

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - usb: cdns3: gadget: fix state inconsistency on gadget init failure When cdns3gadgetstart fails, the DRD hardware is left in gadget mode while software state...

CVE-2026-31772

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI synchronization. A local user could trigger a stack buffer overflow by binding a specific type of Bluetooth socket with an excessive number of Bluetooth Isochronous Stream BIS entries. This memory corruption can lead t...

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...

CVE-2026-31754

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: gadget: fix state inconsistency on gadget init failure When cdns3gadgetstart fails, the DRD hardware is left in gadget mode while software state remains INACTIVE, creating hardware/software state inconsistency. When...

EUVD-2026-26618

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: fix potential UAF in setcigparamssync hciconn lookup and field access must be covered by hdev lock in setcigparamssync, otherwise it's possible it is freed concurrently. Take hdev lock to prevent hciconn from...

CVE-2026-31754

The CVE-2026-31754 issue affects the Linux kernel’s USB DRD/CDNS3 gadget path. When cdns3_gadget_start() fails, the DRD hardware remains in gadget mode while software state is INACTIVE, causing hardware/software state inconsistency. This can lead to a failed host-mode switch via sysfs (role switc...
