CVE-2026-23315

A flaw was found in the Linux kernel's mt76 Wi-Fi driver. This vulnerability, an out-of-bounds OOB access, occurs due to an insufficient check of frame length before accessing management fields within the mt76connac2macwritetxwi80211 function. An attacker could potentially exploit this to cause...

CVE-2026-27889

CVE-2026-27889 pertains to the NATS server when WebSockets are enabled. A pre-authentication remote crash can be triggered by a crafted WebSocket frame with a 64-bit extended payload length MSB set, which causes a signed/unsigned handling issue and results in an unrecovered panic, terminating the...

CVE-2026-27889 NATS: Pre-auth remote server crash via WebSocket frame length overflow in wsRead

NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Starting in version 2.2.0 and prior to versions 2.11.14 and 2.12.5, a missing sanity check on a WebSockets frame could trigger a server panic in the nats-server. This happens before authentication, and...

CVE-2026-23307

A flaw was found in the Linux kernel's emsusb module. This vulnerability occurs because the system does not properly verify the length of messages it receives. An attacker could exploit this weakness by sending specially crafted messages, potentially causing the system to crash Denial of Service...

SUSE CVE-2026-23298

In the Linux kernel, the following vulnerability has been resolved: can: ucan: Fix infinite loop from zero-length messages If a broken ucan device gets a message with the message length field set to 0, then the driver will loop for forever in ucanreadbulkcallback, hanging the system. If the lengt...
