CVE-2025-38177

In the Linux kernel, the following vulnerability has been resolved: sch_hfsc: make hfsc_qlen_notify() idempotent hfsc_qlen_notify() is not idempotent either and not friendly to its callers, like fq_codel_dequeue(). Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers' life: 1. update_vf() decreases cl->cl_nactive, so we can check whether it is non-zero before calling it. 2. eltree_remove() always removes RB node cl->el_node, but we can use RB_EMPTY_NODE() + RB_CLEAR_NODE() to make it safe.

Security Fix(es):

A vulnerability was found in Linux Kernel up to 6.15.3 (Operating System). It has been rated as problematic.Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.Impacted is confidentiality, integrity, and availability.Upgrading to version 5.4.295, 5.10.239, 5.15.186, 6.1.142, 6.6.95, 6.12.35, 6.15.4 or 6.16-rc1 eliminates this vulnerability. Applying the patch 119766de4930ff40db9f36b960cb53b0c400e81b/33163c68d2e3061fa3935b5f0a1867958b1cdbd2/9da3e442714f7f4393ff01c265c4959c03e88c2f/9a350f30d65197354706b7759b5c89d6c267b1a9/6bd2569d0b2f918e9581f744df0263caf73ee76c/4da7fcc098218ff92b2e83a43f545c02f714cedd/cdaa6d1cb2ff1219c6c822b27655dd170ffb0f72/9ad0452c0277b816a435433cca601304cfac7c21 is able to eliminate this problem.

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.

Security Fix(es):

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

gtp: Destroy device along with udp socket's netns dismantle.

gtp_newlink() links the device to a list in dev_net(dev) instead of src_net, where a udp tunnel socket is created.

Even when src_net is removed, the device stays alive on dev_net(dev). Then, removing src_net triggers the splat below. [0]

In this example, gtp0 is created in ns2, and the udp socket is created in ns1.

Let's link the device to the socket's netns instead.

The Linux Kernel, the operating system core itself.

Security Fix(es):

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.(CVE-2025-21934)

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

cifs: Fix integer overflow while processing closetimeo mount option

User-provided mount parameter closetimeo of type u32 is intended to have an upper limit, but before it is validated, the value is converted from seconds to jiffies which can lead to an integer overflow.

Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2025-21962)

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

ksmbd: fix use-after-free in ksmbd_free_work_struct

->interim_entry of ksmbd_work could be deleted after oplock is freed. We don't need to manage it with linked list. The interim request could be immediately sent whenever a oplock break wait is needed.(CVE-2025-21967)

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

ksmbd: fix use-after-free in kerberos authentication

Setting sess->user = NULL was introduced to fix the dangling pointer created by ksmbd_free_user. However, it is possible another thread could be operating on the session and make use of sess->user after it has been passed to ksmbd_free_user but before sess->user is set to NULL.(CVE-2025-37924)

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

sch_htb: make htb_qlen_notify() idempotent

htb_qlen_notify() always deactivates the HTB class and in fact could trigger a warning if it is already deactivated. Therefore, it is not idempotent and not friendly to its callers, like fq_codel_dequeue().

Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers' life.(CVE-2025-37932)

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

VMCI: fix race between vmci_host_setup_notify and vmci_ctx_unset_notify

During our test, it is found that a warning can be trigger in try_grab_folio as follow:

Digging into the source, context->notify_page may init by get_user_pages_fast and can be seen in vmci_ctx_unset_notify which will try to put_page. However get_user_pages_fast is not finished here and lead to following try_grab_folio warning. The race condition is shown as follow:

cpu0 cpu1 vmci_host_do_set_notify vmci_host_setup_notify get_user_pages_fast(uva, 1, FOLL_WRITE, &context->notify_page); lockless_pages_from_mm gup_pgd_range gup_huge_pmd // update &context->notify_page vmci_host_do_set_notify vmci_ctx_unset_notify notify_page = context->notify_page; if (notify_page) put_page(notify_page); // page is freed __gup_longterm_locked __get_user_pages follow_trans_huge_pmd try_grab_folio // warn here

To slove this, use local variable page to make notify_page can be seen after finish get_user_pages_fast.(CVE-2025-38102)
