CVE-2026-97587

A flaw was found in the Linux kernel's RISC-V performance monitoring perf subsystem. On 32-bit RISC-V systems, the available counter mask was stored in a 32-bit data structure while the subsystem iterated over up to 64 counters, resulting in an out-of-bounds memory read. A local user could exploi...

DeadDialect

DeadDialect 매 부팅은 다른 언어를 말한다. 어제의 바이너리는 오늘의 죽은 코드다. 세션 고유의 RISC-V ISA 재매핑 시스템. 시스템이 부팅될 때마다 명령어 집합의 새로운 암호화 순열을 생성합니다. 한 세션용으로 컴파일된 바이너리는 다음 세션에서 암호학적으로 거부됩니다. 재부팅 후에도 살아남는 멀웨어는 실행될 수 없습니다 — 죽은 방언을 말하기 때문입니다. 아이디어 표준 ISA는 고정된 계약입니다. 모든 프로그램, 모든 라이브러리, 모든 멀웨어는 0x13의 의미, syscall 64의 기능, 스택 포인터가 어떤...
