CVE-2026-68329

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Wait for completion instead of returning early in iommucompletionwait needsync is a per-IOMMU flag shared by all domains and devices behind that IOMMU. It is set whenever a command is queued with sync == true and clear...

CVE-2026-68329

CVE-2026-68329 affects the Linux kernel’s iommu/amd path. A race in iommu_completion_wait() can cause it to return before all previously queued commands complete, enabling a use-after-free window where stale page-table translations may be used. The issue stems from need_sync being read locklessly...

CVE-2026-64024

A flaw was found in the Linux kernel's Transmission Control Protocol TCP networking stack. This vulnerability arises from a stale per-CPU variable that can retain a previously used Initial Sequence Number ISN when certain packets are dropped. A remote attacker could exploit this by sending...

CVE-2026-64024

CVE-2026-64024 concerns a Linux kernel issue where a per-CPU tcp_tw_isn leak could enable ISN prediction. The root cause was that TIME_WAIT-derived ISNs were stored in a per-CPU variable and could be consumed by a subsequent SYN if a packet was dropped along several paths (e.g., min_ttl/min_hop, ...
