CVE-2026-74632

A flaw was found in the Linux kernel's memory management mm/hugememory. A race condition can occur between a memory shrinker and a concurrent page fault when handling huge zero pages. This race can lead to the hugezeropfn being incorrectly set, causing the huge zero page to be misidentified as an...

CVE-2026-74599

A flaw was found in the Linux kernel's memory management subsystem. A race condition exists in the ptdump mechanism, specifically when ptdumpwalkpgd is used on non-initial memory management structures on x86 and arm64 architectures. This allows for a race between ptdump and kernel page table...

CVE-2026-74715

A flaw was found in the kernel. A reference imbalance vulnerability exists in the Berkeley Packet Filter BPF conntrack kfuncs. This occurs when the 'opts' argument, which can point to a shared map value, has its network namespace identifier netnsid read separately during reference acquisition and...
