In the Linux kernel, the following vulnerability has been resolved: mm: fix a UAF when vma->mm is freed after vma->vm_refcnt got dropped By inducing delays in the right places, Jann Horn created a reproducer for a hard to hit UAF issue that became possible after VMAs were allowed to be recycled by adding SLAB_TYPESAFE_BY_RCU to their cache. Race description is borrowed from Jann's discovery report: lock_vma_under_rcu() looks up a VMA locklessly with mas_walk() under rcu_read_lock(). At that point, the VMA may be concurrently freed, and it can be recycled by another process. vma_start_read() then increments the vma->vm_refcnt (if it is in an acceptable range), and if this succeeds, vma_start_read() can return a recycled VMA. In this scenario where the VMA has been recycled, lock_vma_under_rcu() will then detect the mismatching ->vm_mm pointer and drop the VMA through vma_end_read(), which calls vma_refcount_put(). vma_refcount_put() drops the refcount and then calls rcuwait_wake_up() using a copy of vma->vm_mm. This is wrong: It implicitly assumes that the caller is keeping the VMA's mm alive, but in this scenario the caller has no relation to the VMA's mm, so the rcuwait_wake_up() can cause UAF. The diagram depicting the race: T1 T2 T3 == == == lock_vma_under_rcu mas_walk <VMA gets removed from mm> mmap <the same VMA is reallocated> vma_start_read __refcount_inc_not_zero_limited_acquire munmap __vma_enter_locked refcount_add_not_zero vma_end_read vma_refcount_put __refcount_dec_and_test rcuwait_wait_event <finish operation> rcuwait_wake_up [UAF] Note that rcuwait_wait_event() in T3 does not block because refcount was already dropped by T1. At this point T3 can exit and free the mm causing UAF in T1. To avoid this we move vma->vm_mm verification into vma_start_read() and grab vma->vm_mm to stabilize it before vma_refcount_put() operation. [surenb@google.com: v3]

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: mm: fix a UAF when vma->mm is freed     after vma->vm_refcnt got dropped By inducing delays in the right places, Jann Horn created a reproducer     for a hard to hit UAF issue that became possible after VMAs were allowed to be recycled by adding     SLAB_TYPESAFE_BY_RCU to their cache. Race description is borrowed from Jann's discovery report:
    lock_vma_under_rcu() looks up a VMA locklessly with mas_walk() under rcu_read_lock(). At that point, the     VMA may be concurrently freed, and it can be recycled by another process. vma_start_read() then increments     the vma->vm_refcnt (if it is in an acceptable range), and if this succeeds, vma_start_read() can return a     recycled VMA. In this scenario where the VMA has been recycled, lock_vma_under_rcu() will then detect the     mismatching ->vm_mm pointer and drop the VMA through vma_end_read(), which calls vma_refcount_put().
    vma_refcount_put() drops the refcount and then calls rcuwait_wake_up() using a copy of vma->vm_mm. This is     wrong: It implicitly assumes that the caller is keeping the VMA's mm alive, but in this scenario the     caller has no relation to the VMA's mm, so the rcuwait_wake_up() can cause UAF. The diagram depicting the     race: T1 T2 T3 == == == lock_vma_under_rcu mas_walk <VMA gets removed from mm> mmap <the same VMA is     reallocated> vma_start_read __refcount_inc_not_zero_limited_acquire munmap __vma_enter_locked     refcount_add_not_zero vma_end_read vma_refcount_put __refcount_dec_and_test rcuwait_wait_event <finish     operation> rcuwait_wake_up [UAF] Note that rcuwait_wait_event() in T3 does not block because refcount was     already dropped by T1. At this point T3 can exit and free the mm causing UAF in T1. To avoid this we move     vma->vm_mm verification into vma_start_read() and grab vma->vm_mm to stabilize it before     vma_refcount_put() operation. [surenb@google.com: v3] (CVE-2025-38554)

Note that Nessus relies on the presence of the package as reported by the vendor.
