CVE-2026-53057 CWE-524 kernel: iommu/riscv: Add IOTINVAL after updating DDT/PDT entries
kernel: iommu/riscv: Add IOTINVAL after updating DDT/PDT entries
A flaw was found in the Linux kernel, specifically within the Input/Output Memory Management Unit (IOMMU) for RISC-V architectures. This vulnerability occurs because the system does not properly clear out old memory translation information, known as Translation Lookaside Buffer (TLB) and context cache entries, after updating critical memory tables. An attacker could potentially exploit this oversight to access or alter data incorrectly, leading to data integrity issues or the disclosure of sensitive information.
