fkie_cve-2025-21934

In the Linux kernel, the following vulnerability has been resolved:

rapidio: fix an API misues when rio_add_net() fails

rio_add_net() calls device_register() and fails when device_register() fails. Thus, put_device() should be used rather than kfree(). Add "mport->net = NULL;" to avoid a use after free issue.

OESA-2025-2118 — kernel security update

Affected: openEuler:22.03-LTS-SP3: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: avoid skb access on nf_stolen

When verdict is NF_STOLEN, the skb might have been freed.

When tracing is enabled, this can result in a use-after-free: 1. access to skb->nf_trace 2. access to skb->mark 3. computation of trace id 4. dump of packet payload

To avoid 1, keep a cached copy of skb->nf_trace in the trace state struct. Refresh this copy whenever verdict is != STOLEN.

Avoid 2 by skipping skb->mark access if verdict is STOLEN.

3 is avoided by precomputing the trace id.

Only dump the packet when verdict is not "STOLEN".(CVE-2022-49622)

In the Linux kernel, the following vulnerability has been resolved:

nfsd: release svc_expkey/svc_export with rcu_work

The last reference for `cache_head` can be reduced to zero in `c_show` and `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently, `svc_export_put` and `expkey_put` will be invoked, leading to two issues:

1. The `svc_export_put` will directly free ex_uuid. However, `e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can trigger a use-after-free issue, shown below.
