CVE-2026-23415

The CVE-2026-23415 issue affects the Linux kernel futex subsystem. A race occurs between futex_key_to_node_opt() reading vma->vm_policy under speculative mmap lock/RCU and mbind() calling vma_replace_policy(), which can free the old mempolicy via kmem_cache_free(). This leads to a use-after-fr...

The vulnerability of the __rb_map_vma() function in the kernel/trace/ring_buffer.c module, which supports Linux operating system kernel tracing, allows a hacker to cause a service failure.

The vulnerability of the rbmapvma function in the kernel/trace/ringbuffer.c module, which supports kernel tracing in Linux operating systems, is related to the execution of operations outside the buffer boundaries. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the `register_for_each_vma()` function in the kernel/events/uprobes.c module, which manages kernel events in Linux operating systems, allows a attacker to cause a service failure.

The vulnerability of the registerforeachvma function in the kernel/events/uprobes.c module, which handles kernel event handling in Linux operating systems, is related to the distribution of resources without any restrictions or regulation. Exploiting this vulnerability could allow an attacker to...
