Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; -...

CVE-2026-53312

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit component for RISC-V architectures. An integer overflow in the invalidation path can lead to an infinite loop. This vulnerability could allow a local attacker to cause a Denial of Service DoS by triggering the overfl...

EUVD-2026-39847

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Remove overflows on the invalidation path Since RISC-V supports a sign extended page table it should support a gather-end of ULONGMAX, but if this happens it will infinite loop because of the overflow. Also avoid...
