Original: ⚪️ New Spectre v2 Variant Threatens Intel, AMD, and Arm Processors 🗨️ A new variant of the Spectre v2 side-channel attac
Security researchers have disclosed a new variant of the Spectre v2 side-channel attack, dubbed Branch Target Reuse (BTR), which can extract secrets from memory through just-in-time (JIT) compilation engines. The flaw affects processors from Intel, AMD, and Arm. Researchers have demonstrated two working exploits, raising concerns about patching challenges across affected chip platforms.
Why now: A newly disclosed hardware attack variant affecting all major chipmakers is significant security news with potential patching implications.
