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...

CVE-2026-53312

The CVE-2026-53312 issue affects the Linux kernel in the iommu/riscv invalidation path. The root cause is integer overflow when handling sign-extended page tables (ULONG_MAX) that could lead to an infinite loop during invalidation. The patch removes these overflows and relocates the +1 to avoid l...

PT-2026-52951

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the RISC-V IOMMU invalidation path. Because RISC-V supports sign extended page tables, a gather-end value of ULONG MAX can cause an infinite loop due to an integer...

kernel: Linux kernel: Denial of Service in mlx5e due to incorrect encap attribute handling

A flaw was found in the mlx5e Traffic Control TC encapsulation logic in the net/mlx5e driver of the Linux kernel. The code responsible for invalidating encapsulation actions did not use the proper helper function to retrieve the correct encapsulation attribute, instead assuming the default...
