Group 1: Price Trends - Samsung and SK Hynix have indicated that the contract prices for DRAM and NAND are likely to rise, with expectations for announcements by the end of January or early February [3]. - The market speculation regarding an 80% price increase from Samsung remains unverified, as Taiwanese module manufacturers and agents have not received formal price notifications [3]. - By the first quarter of 2026, both DRAM and NAND prices are anticipated to trend upwards, with a clear upward price cycle in place [3][4]. Group 2: Price Structure and Client Impact - The actual price increases will vary by customer tier, with cloud service providers (CSPs) and high-end applications facing higher price hikes, while module and channel levels will experience more moderate increases [4]. - The pricing strategy is shifting towards a seller's market, as evidenced by the rapid rise in RDIMM spot prices and the requirement for some NAND customers to make deposits to secure allocations [4]. Group 3: Contract Strategies and Market Behavior - Current practices involve manufacturers and clients adopting long-term contracts to secure annual capacity, but historical trends suggest that clients may not always fulfill their commitments if market conditions change [5]. - The focus is shifting from merely signing long-term contracts to designing contracts that ensure actual shipment feasibility, including minimum order quantities, prepayments, priority supply terms, and cancellation clauses [5]. - To mitigate the risk of overbooking, Taiwanese storage manufacturers and module factories are implementing allocation strategies based on historical shipment records to ensure smooth supply and risk management [5].

Core Viewpoint - The article highlights the emergence of the StackWarp vulnerability affecting multiple AMD ZEN architecture processors, emphasizing the ongoing security risks within the X86 ecosystem. It contrasts this with the immunity demonstrated by domestic CPU manufacturer Haiguang, which has been confirmed to be unaffected by this vulnerability [1][3]. Group 1: Vulnerability Overview - The StackWarp vulnerability, discovered by Germany's CISPA Helmholtz Center for Information Security, allows malicious VM hosts to manipulate the stack pointer of customer virtual machines, enabling remote code execution and privilege escalation within confidential virtual machines [3]. - AMD's SEV-SNP is identified as a critical entry point for this vulnerability, where attackers can alter the RSP register to control execution flow and data within the virtual machine [3][4]. - AMD has acknowledged the vulnerability and stated that low-risk patches have been available for EPYC products since July of the previous year [3]. Group 2: Haiguang's Immunity - Haiguang's CPU, which holds complete X86 licensing, has been noted for its natural immunity to the StackWarp vulnerability due to its proprietary CSV virtualization technology, which fundamentally differs from AMD's SEV-SNP [3][4]. - The article emphasizes that Haiguang's CSV3 technology has effectively closed the attack vectors that StackWarp exploits, showcasing the importance of domestic innovation in CPU security [4].
