cgroup: Avoid iteration of dying tasks with zero refcount
The commit 260fbcb92bbea ("cgroup: Move dying_tasks cleanup from
cgroup_task_release() to cgroup_task_free()") extended the lifetime of
tasks on the dying_tasks list.
The iterators have provision to go through dying_tasks because of
dying threadgroup leaders or explicit CSS_TASK_ITER_WITH_DEAD, however,
it was expected that such tasks can obtain a new reference (that is
possible before cgroup_task_release()/put_task_struct_rcu_user()).
The tasks after cgroup_task_release() and before cgroup_task_free()
are subject to race when they may or may not have ->usage count > 0.
The race window is between css_task_iter_next() invocations
when css_set_lock is released and we may arrive at a new ->task_pos.
The iterator should not attempt to resurrect tasks whose ->usage count
dropped to zero. (When that happens, __put_task_struct_rcu_cb() is
already imminent and the returned task_struct would could be used
after free.)
As for the fix, we cannot simply check the signal->live count of a task
on the dying list because that won't distinguish regular zombies waiting
to be reaped from RCU remnant tasks that are going to be free'd.
Therefore add an extra check to rule out ->usage==0 tasks from any
iteration.
The repeat: loop in css_task_iter_advance() doesn't consider ->usage
count, so add a new loop to css_task_iter_next() to skip de-used tasks
on the dying_list.
Rough illustration of the possible race
R (reader of cgroup.procs) T (thread) L (group leader)
--------------------------------- -------------------------------- --------------------------------
L exits, signal->live > 0
cgroup_task_dead(L)
css_set_skip_task_iters() // skips only cset->tasks
list_add_tail(&L->cg_list, &cset->dying_tasks)
css_task_iter_next()
take css_set_lock
css_task_iter_advance()
leader && signal->live != 0
=> it->task_pos = &L->cg_list
release css_set_lock
T exits
--signal->live == 0
cgroup_task_dead(T) // css_set_lock
release_task(T)
cgroup_task_release(T)
release_task(L) // zap_leader
cgroup_task_release(L)
put_task_struct_rcu_user(L)
...RCU...
put_task_struct(L)
L->usage = 0
/* L still on dying_tasks */
...RCU...
__put_task_struct(L)
css_task_iter_next() // another iteration
take css_set_lock
it->task_pos = &L->cg_list
get_task_struct(L)
=> addition on 0
drop css_set_lock
cgroup_task_free(L)
css_set_skip_task_iters() // dying skip comes too late
free_task(L)

| The Nexi XPay Build WordPress plugin through 7.6.2 does not correctly validate the security token on its payment notification route, accepting the request when the target order has no stored token, which allows unauthenticated attackers to mark arbitrary orders as paid, or to mark genuinely paid orders as failed. |
| The Nexi XPay Build WordPress plugin through 7.6.2 does not verify the payment result supplied to several of its unauthenticated routes, allowing attackers to mark arbitrary orders as paid or failed, to cancel them, and to obtain order keys which expose guest buyers' details. |
| The Magee Shortcodes WordPress plugin through 2.1.1 does not restrict the recipient of some of its unauthenticated contact-form actions, allowing unauthenticated users to send arbitrary emails to any address through the site (mail relay). |
| The MetForm WordPress plugin before 4.3.1 does not sanitize or escape submitted form-field values before inserting them into the HTML body of its email notifications, allowing unauthenticated attackers to inject arbitrary markup into the administrator and submitter notification emails the site sends. |
| Oracle VM VirtualBox before 7.2.8 allows guest OS users to cause an out-of-bounds write in the host OS in pcnetReceiveNoSync in DevPCNet.cpp in the PCNet (Am79C970A) network device model. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix out-of-bounds read in P2P public action frames
wilc_wfi_p2p_rx() and mgmt_tx() start parsing a frame once
ieee80211_is_public_action() returns true. That helper only verifies the
frame is long enough for the action category field, that is
offsetofend(struct ieee80211_mgmt, u.action.category), 25 bytes. Both
functions then read the P2P public action header up to oui_subtype at
offset 30 and pass "size - ie_offset" to cfg80211_find_vendor_ie(), where
ie_offset is offsetof(struct ieee80211_mgmt, u) + sizeof(*d), i.e. 32.
A public action frame of 25 to 31 bytes passes the check but is shorter
than that 32 byte header, so oui_subtype can be read out of bounds, and
because the length is unsigned, "size - ie_offset" underflows to a value
close to 4 GiB. cfg80211_find_vendor_ie() takes an unsigned int length,
so even the size_t subtraction in mgmt_tx() is truncated to the same
value. It then walks far past the buffer searching for a vendor element
until it reaches unmapped memory.
In the receive path the frame arrives over the air and needs no
association, so a nearby unauthenticated device can crash the host while
it is in P2P listen. Reject frames shorter than the P2P public action
header in both paths before dereferencing it. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wlcore: release runtime PM ref on regdomain config failure
wlcore_regdomain_config() gets a runtime PM reference before sending
the regulatory-domain command. When
wlcore_cmd_regdomain_config_locked() fails, the function queues recovery
and returns without dropping that reference.
Release the reference after handling the command result so both success
and failure paths balance the preceding
pm_runtime_resume_and_get(). The recovery worker takes a separate
runtime PM reference and cannot release the reference held here. |
| SimpleChat is a secure AI conversation application with personal and group workspaces for document-grounded interactions. In versions 0.261.003 and 0.261.027, an authorization ordering flaw in POST /api/user/plugins allows an authenticated low-privileged user to omit the top-level MCP type so that _reject_non_admin_mcp_stdio skips inspection before the type is restored from metadata. The stored personal action can then reach McpPluginFactory.create_connector, and MCPStdioPlugin.connect starts the attacker-selected operating-system process under the application service identity when the action tool is invoked. Exploitation requires personal plugins to be enabled and governance to permit MCP actions, and it can expose or modify secrets and data available to the service or disrupt the service. This issue is fixed in version 0.261.031. |
| SimpleChat is a secure AI conversation application with personal and group workspaces for document-grounded interactions. Prior to 0.261.029, POST /api/group_documents/upload stores an attacker-controlled group document filename that group_workspaces.html later interpolates into inline Share event handlers. The escapeGroupHtml function leaves apostrophes unchanged, while escapeHtml produces an HTML entity that the browser decodes before JavaScript evaluation, so either path permits the filename to terminate the handler string. An authenticated group Owner, Admin, or DocumentManager can persist script that executes in the SimpleChat origin when another group member clicks Share, allowing access to victim-visible data and actions with the victim session. This issue is fixed in version 0.261.029. |

| Payload is a free and open source headless content management system. Payload versions from 3.0.0 before 3.90.0 and canary versions from 4.0.0-canary.0 before 4.0.0-canary.34 use a lower-than-recommended PBKDF2 work factor for password hashing, reducing the computational effort required to test recovered password hashes. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34. |

| Payload is a free and open source headless content management system. In versions after 3.0.0 and before 3.90.0, authenticated external URL-based upload retrieval can forward authentication data to a redirected destination that was not verified as trusted, potentially exposing a valid session to an unintended recipient. This issue is fixed in version 3.90.0. |
| Payload is a free and open source headless content management system. In @payloadcms/db-mongodb versions before 3.87.0 and canary versions before 4.0.0-canary.20, an authenticated user who can update a document can modify fields that field-level write access control does not permit that user to change. The Postgres and SQLite adapters are not affected. This issue is fixed in versions 3.87.0 and 4.0.0-canary.20. |
