CVE-2026-90052

CVE-2026-90052 is a buffer overflow in the Linux kernel's dm-integrity subsystem. Since commit 68c5c42567bc, integrity_metadata computes a checksum for every discarded block, but integrity_sector_checksum always writes the full digest regardless of the configured tag size. When the tag size is sm...

kernel: dm_early_create: fix freeing used table on dm_resume failure

A flaw was found in the Linux kernel's device mapper DM subsystem. During certain resume operations, the kernel might attempt to free a memory table that has already been released. This error, known as a double-free vulnerability, can lead to memory corruption. A successful exploit could result i...

Experimental Demonstration of Finite-Size General Security Via Discrete-Modulated CVQKD with Real Time Postprocessing

Continuous-variable quantum key distribution CVQKD is compatible with telecommunication infrastructure, but implementing composable security with experimentally practical resources has remained challenging, particularly for discrete-modulated DM protocols. We report the first experimental...
