Chinese Loongson Processors Exhibit Cache Leaks, Researchers Warn
Loongson processors have been found to have leaky caches, allowing attackers to access sensitive data. Researchers from Germany's Helmholtz Center report the vulnerability.
Researchers from Germany's Helmholtz Center for Information Security have discovered that processors from China's Loongson feature leaky caches that attackers could exploit to access specific data. The LoongArch instruction set architecture developed by Loongson combines elements from MIPS and RISC-V. The researchers indicate that this vulnerability can be exploited from unprivileged user space, potentially compromising sensitive information across virtual machine boundaries.
