      "title": "rust: devres: fix race between concurrent revokers",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nrust: devres: fix race between concurrent revokers\n\nThere is a potential race condition when two paths try to revoke a\nDevres concurrently.\n\nThe driver core's devres_release_all() calls Revocable::revoke() via the\nrelease callback, while Devres::drop() calls revoke_nosync() on another\nCPU.\n\nThe revoker that does not claim the is_available swap returns\nimmediately, but the revoker that did may still be executing\ndrop_in_place() on the inner data. This can cause a use-after-free when\nthe other revoker's caller proceeds to drop adjacent resources that\ndrop_in_place() still references (e.g., Devres<DmaMappedSgt> racing with\nSGTable freeing the backing sg_table and pages).\n\nFix this by adding a Completion. The release callback signals the\nCompletion after revoke() finishes, and Devres::drop() waits for it when\nit loses the is_available swap. This ensures the wrapped object is fully\ntorn down before Devres::drop() returns.",
