[PATCH openEuler-1.0-LTS] nfsd: make sure exp active before svc_export_show
by Li Lingfeng 24 Feb '25

24 Feb '25

From: Yang Erkun <yangerkun(a)huawei.com> mainline inclusion from mainline-v6.13-rc1 commit be8f982c369c965faffa198b46060f8853e0f1f0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAMQ CVE: CVE-2024-56558 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The function `e_show` was called with protection from RCU. This only ensures that `exp` will not be freed. Therefore, the reference count for `exp` can drop to zero, which will trigger a refcount use-after-free warning when `exp_get` is called. To resolve this issue, use `cache_get_rcu` to ensure that `exp` remains active. ------------[ cut here ]------------ refcount_t: addition on 0; use-after-free.
