CVE-2026-53312

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 overflow. Additionally, an overflow can occur during length computation when using a less-than operator with an incremented value.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
