UBUNTU-CVE-2026-22858

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, global-buffer-overflow was observed in FreeRDP's Base64 decoding path. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char is treated as unsigned, so the guard c = ...

RUSTSEC-2026-0003 Non-constant-time code generation on ARM32 targets

Summary While the cmov crate has a special backend for aarch64 which uses special CSEL instructions, on 32-bit ARM it uses a portable pure Rust fallback implementation. This implementation uses a combination of bitwise arithmetic and core::hint::blackbox to attempt to coerce constant-time code...

CVE-2025-0647

In certain Arm CPUs, a CPP RCTX instruction executed on one Processing Element PE may inhibit TLB invalidation when a TLBI is issued to the PE, either by the same PE or another PE in the shareability domain. In this case, the PE may retain stale TLB entries which should have been invalidated by t...
