CVE-2026-53084

In the Linux kernel, the following vulnerability has been resolved: bpf: return VMA snapshot from taskvma iterator Holding the per-VMA lock across the BPF program body creates a lock ordering problem when helpers acquire locks that depend on mmaplock: vmlock - irwsem - mmaplock - vmlock Snapshot...

In the Linux kernel, the following vulnerability has been resolved: bpf: return VMA snapshot from taskvma iterator Holding the per-VMA lock across the BPF program body creates a lock ordering problem when helpers acquire locks that depend on mmaplock: vmlock - irwsem - mmaplock - vmlock Snapshot...

CVE-2026-53084

The Linux kernel CVE-2026-53084 is addressed by changing the VMA snapshot handling in the task_vma iterator used by BPF. The per-VMA lock is no longer held across the BPF program body; instead, the VMA is snapshot via memcpy() under the lock in _next(), and the lock is dropped before returning. T...
