CVE-2026-53312

In CVE-2026-53312, a Linux kernel iommu/riscv vulnerability is resolved: an integer overflow in the invalidation path could cause an infinite loop when handling sign-extended page tables (ULONG_MAX) during a gather/end computation. The fix moves the +1 away from the potentially overflowed compari...

CVE-2026-53057

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 cach...

CVE-2026-53312: Undefined Security Weakness

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...
