CVE-2026-45837

CVE-2026-45837 : In the Linux kernel, a use-after-free in arena_vm_close on fork was fixed. The root cause is that arena_vm_open() only bumps vml->mmap_count and does not register the child VMA in arena->vma_list, so vml->vma continues to point to the parent VMA after fork. If the child ...
