CVE-2026-10680

The Classic BR/EDR L2CAP signaling handlers l2capbrconfreq and l2capbrconfrsp in subsys/bluetooth/host/classic/l2capbr.c validated the minimum command size against buf-len the bytes remaining in the whole received PDU instead of len the per-command data length from the L2CAP signaling header...

CVE-2026-63940

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV module. This vulnerability occurs because the system does not properly handle Port I/O requests with a length of zero. An attacker, potentially from a guest virtual machine, could exploit...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the NonBlockingUtf8JsonParserBase file. An attacker can exhaust system memory by streaming JSON input in small chunks to the asynchronous parser, causing unbounded accumulation of...
