kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

CVE-2026-74573

Concise summary: CVE-2026-74573 affects the Linux kernel IOMMU arm-smmu-v3-iommufd. The vulnerability arises when a vDEVICE is mapped to more than one stream: arm_vsmmu_vsid_to_sid() uses only master->streams[0], so guests with multiple streams may not invalidate all ATC/IOTLB entries; if ther...
