SUSE CVE-2026-13322

A flaw was found in KubeVirt's downward metrics virtio-serial server. The server reads guest requests using textproto.Reader.ReadLine, which buffers input indefinitely until a newline character is received, with no length limit or read deadline. A user with access to a VM guest that has the...

CVE-2026-38571

Cleartext storage and exposure of WPA2 credentials, and missing authentication on the rr/wr memory read/write commands, in the unauthenticated UART debug console of the Tenda N300 F3 V603 allow a physically proximate attacker to obtain stored WPA2 credentials in cleartext and to read or write...

CVE-2026-53037

A flaw was found in the Linux kernel's USB Human Interface Device HID subsystem. This vulnerability occurs when a USB device, containing both HID and storage or Universal Attached SCSI UAS components, is reset. During the reset process, memory allocation operations within the hidpostreset functio...

CVE-2026-53194

A flaw was found in the Linux kernel's kl5kusb105 USB serial driver. This buffer overflow vulnerability allows a local attacker to write data beyond the intended memory boundary if attacker controls USB device or driver, because triggered from the internals of the device. By sending a specially...

SUSE CVE-2026-53037

In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix deadlock in hidpostreset You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hidprereset and hidpostreset are in the...

OCSP CertID serial-number length-confusion in wolfSSLOCSPrespfindstatus allows a same-issuer SingleResponse whose serial is a prefix of the target serial to be reported as the revocation status of a different certificate. The lookup compared serial-number bytes without first requiring the two...

CVE-2026-53195

A flaw was found in the USB: serial: ioti module of the Linux kernel. The buildi2cfwhdr function allocates a fixed-size buffer but copies data into it without properly validating the input length from the firmware header. This oversight allows an attacker to provide a crafted firmware image,...
