CVE-2025-38554

CVE-2025-38554 in the Linux kernel describes a use-after-free (UAF) involving VMAs: if vma->mm is freed after vma->vm_refcnt has dropped, a recycled VMA could be mishandled, leading to UAF. The race can occur when VMAs are recycled under RCU (with SLAB_TYPESAFE_BY_RCU) and lock_vma_under_rc...
