EUVD-2026-108887

In the Linux kernel, the following vulnerability has been resolved: arm64: io: Reject non-user protection in ioremapprot Mapping a stack-top page via /dev/mem with PROTNONE and then reading that process's /proc//cmdline triggers a spurious WARN in ioremapprot through genericaccessphys: WARNING:...

CVE-2026-98923

In the Linux kernel, the following vulnerability has been resolved: arm64: io: Reject non-user protection in ioremapprot Mapping a stack-top page via /dev/mem with PROTNONE and then reading that process's /proc//cmdline triggers a spurious WARN in ioremapprot through genericaccessphys: WARNING:...

CVE-2026-98923

The Linux kernel (arm64 architecture) contains a vulnerability where mapping a stack-top page via /dev/mem with PROT_NONE and subsequently reading /proc//cmdline triggers a spurious WARN in ioremap_prot(). This occurs because generic_access_phys() passes protection from a present-invalid PTE to i...
