CVE-2026-99017
A flaw was found in the Linux kernel. Under specific configurations on RISC-V systems using T-Head processors, the kernel does not execute early boot checks required to identify hardware errata. As a result, the default mitigation for the Ghostwrite hardware vulnerability is not applied, which ma...

CVE-2026-99017
The Linux kernel contains a vulnerability where the T-Head C9xx CPU might not have its ghostwrite mitigation applied correctly. The root cause is that errata_probe_ghostwrite() only marks the CPU as vulnerable during the RISCV_ALTERNATIVES_EARLY_BOOT stage. In kernels where ERRATA_THEAD_GHOSTWRIT...

Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 6.14. It arises when RISCVALTERNATIVEEARLY is not selected when ERRATATHEADGHOSTWRITE is enabled but ERRATATHEADMAE is not. As a result, the GHOSTWRITE vulnerability on T-head C9xx CPUs is not detected during the early boot phase. No...
