SUSE CVE-2026-68389

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciqca: Clear memdump state on invalid dump size qcacontrollermemdump allocates qca-qcamemdump before processing the first dump packet. For a sequence-zero packet it then disables IBS, marks memdump collection active,...

CVE-2026-68389

A flaw was found in the Bluetooth Host Controller Interface HCI Qualcomm Atheros QCA driver within the Linux kernel. This vulnerability occurs when the controller reports an invalid zero memory dump size, leading to improper state cleanup. An attacker could potentially exploit this to cause memor...

CVE-2026-64573

A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the qca driver. A local attacker could exploit an integer underflow vulnerability in the NVM tag length parser by providing specially crafted firmware data. This could lead to an out-of-bounds memory write, potentiall...
