powerpc/64s: Fix unmap race with PMD migration entries
The following race is possible with migration swap entries or
device-private THP entries. e.g. when move_pages is called on a PMD THP
page, then there maybe an intermediate state, where PMD entry acts as
a migration swap entry (pmd_present() is true). Then if an munmap
happens at the same time, then this VM_BUG_ON() can happen in
pmdp_huge_get_and_clear_full().
This patch fixes that.

| In the Linux kernel, the following vulnerability has been resolved:
net: airoha: Move ndesc initialization at end of airoha_qdma_init_rx_queue()
If queue entry or DMA descriptor list allocation fails in
airoha_qdma_init_rx_queue routine, airoha_qdma_cleanup() will trigger a
NULL pointer dereference running netif_napi_del() for RX queue NAPIs
since netif_napi_add() has never been executed to this particular RX NAPI.
The issue is due to the early ndesc initialization in
airoha_qdma_init_rx_queue() since airoha_qdma_cleanup() relies on ndesc
value to check if the queue is properly initialized. Fix the issue moving
ndesc initialization at end of airoha_qdma_init_tx routine.
Move page_pool allocation after descriptor list allocation in order to
avoid memory leaks if desc allocation fails. |
| The webp decoder can panic when processing a VP8 chunk with dimensions that do not match the canvas size. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu: Fix NULL group->domain dereference in pci_dev_reset_iommu_done()
Local sashiko review pointed it out that group->domain could be NULL when
a default domain fails to allocate during the first probe, which can crash
at domain->ops->attach_dev dereference in __iommu_attach_device() invoked
by pci_dev_reset_iommu_done().
pci_dev_reset_iommu_prepare() is fine as an old_domain pointer can be NULL.
Skip the re-attach in pci_dev_reset_iommu_done() to fix the bug. |
| In the Linux kernel, the following vulnerability has been resolved:
ice: fix NULL pointer dereference in ice_reset_all_vfs()
ice_reset_all_vfs() ignores the return value of ice_vf_rebuild_vsi().
When the VSI rebuild fails (e.g. during NVM firmware update via
nvmupdate64e), ice_vsi_rebuild() tears down the VSI on its error path,
leaving txq_map and rxq_map as NULL. The subsequent unconditional call
to ice_vf_post_vsi_rebuild() leads to a NULL pointer dereference in
ice_ena_vf_q_mappings() when it accesses vsi->txq_map[0].
The single-VF reset path in ice_reset_vf() already handles this
correctly by checking the return value of ice_vf_reconfig_vsi() and
skipping ice_vf_post_vsi_rebuild() on failure.
Apply the same pattern to ice_reset_all_vfs(): check the return value
of ice_vf_rebuild_vsi() and skip ice_vf_post_vsi_rebuild() and
ice_eswitch_attach_vf() on failure. The VF is left safely disabled
(ICE_VF_STATE_INIT not set, VFGEN_RSTAT not set to VFACTIVE) and can
be recovered via a VFLR triggered by a PCI reset of the VF
(sysfs reset or driver rebind).
Note that this patch does not prevent the VF VSI rebuild from failing
during NVM update — the underlying cause is firmware being in a
transitional state while the EMP reset is processed, which can cause
Admin Queue commands (ice_add_vsi, ice_cfg_vsi_lan) to fail. This
patch only prevents the subsequent NULL pointer dereference that
crashes the kernel when the rebuild does fail.

| In the Linux kernel, the following vulnerability has been resolved:
arm_mpam: Check whether the config array is allocated before destroying it
__destroy_component_cfg() is called to free the configuration array.
It uses the embedded 'garbage' structure, which means the array has
to be allocated.
If __destroy_component_cfg() is called from mpam_disable() before the
configuration was ever allocated, then a NULL pointer is dereferenced.
Check for this case and return early if the configuration is not
allocated.
__destroy_component_cfg() also frees the mbwu_state as this is allocated
by __allocate_component_cfg(). As the mbwu_state is allocated after
comp->cfg is set, and is also under mpam_list_lock, only the first
pointer needs checking. |
| Budibase is an open-source low-code platform. Prior to 3.39.12, an unauthenticated visitor of any published Budibase app reads every document of the backing MongoDB, CouchDB, Elasticsearch, DynamoDB-PartiQL, or REST-with-JSON-body collection and, where the builder has published a PUBLIC write query, modifies every document of that collection with one HTTP request. enrichContext at packages/server/src/sdk/workspace/queries/queries.ts:121-138 substitutes parameter values into the raw JSON body of a query, then JSON.parses the result. The validator validateQueryInputs at packages/server/src/api/controllers/query/index.ts:61-71 rejects only Handlebars markers ({{, }}) in user input and does not escape JSON metacharacters (", \, }). A parameter value containing a closing quote and additional keys lifts attacker-controlled fields into the parsed filter object. For Mongo find, the parsed filter passes directly to collection.find() (packages/server/src/integrations/mongodb.ts:506-510). Duplicate-key JSON parsing overrides the builder's {name: "..."} with {name: {$exists: true}} and returns every document. The same primitive against an updateMany query (mongodb.ts:577-585) widens the filter scope to the full collection while the builder-controlled $set body runs against every matched document. The authorized middleware at packages/server/src/middleware/authorized.ts:141-148 short-circuits when the query's role is PUBLIC. CSRF is not enforced on this path. POST /api/v2/queries/:queryId (packages/server/src/api/routes/query.ts:63) accepts the call with no session, only an x-budibase-app-id header that is public from the published-app URL. This vulnerability is fixed in 3.39.12. |
| Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.23, the local internal-storage backend validates user-supplied paths for .. traversal before it converts Windows-style backslashes to forward slashes. An attacker can therefore smuggle a traversal sequence past the guard using backslashes (..\..\..\); the guard sees a harmless string, and the path is only rewritten to ../../../ after validation, immediately before the file is opened. Any authenticated user who can view an execution (the lowest-privilege role) can call GET /api/v1/{tenant}/executions/{executionId}/file?path=… and read any file on the server filesystem readable by the Kestra process, outside the storage sandbox and across every tenant and namespace. This includes the embedded H2 database (all flows, all users, all stored secrets), internal storage of every other tenant/namespace, mounted secret files, and the process environment (/proc/self/environ) which contains configured database and secret-backend credentials. It is a complete breach of Kestra's storage isolation and multi-tenancy boundary. This vulnerability is fixed in 1.0.45 and 1.3.23. |
| Broken Access Control in the devLXDInstancePatchHandler component of Canonical LXD allows an untrusted guest to mount, read, and overwrite another guest's custom storage volume via a crafted device PATCH request over /dev/lxd when security.devlxd.management.volumes is enabled. |
| Incorrect link resolution by display name in the custom PowerShell VPN editor in Devolutions Remote Desktop Manager 2026.2.5 through 2026.2.11 allows an authenticated attacker with write access to a shared workspace to execute a PowerShell script in another user's context via a display name collision with an existing VPN script link. |
| In the Linux kernel, the following vulnerability has been resolved:
net: mana: Use pci_name() for debugfs directory naming
Use pci_name(pdev) for the per-device debugfs directory instead of
hardcoded "0" for PFs and pci_slot_name(pdev->slot) for VFs. The
previous approach had two issues:
1. pci_slot_name() dereferences pdev->slot, which can be NULL for VFs
in environments like generic VFIO passthrough or nested KVM,
causing a NULL pointer dereference.
2. Multiple PFs would all use "0", and VFs across different PCI
domains or buses could share the same slot name, leading to
-EEXIST errors from debugfs_create_dir().
pci_name(pdev) returns the unique BDF address, is always valid, and is
unique across the system. |
| A privilege escalation vulnerability exists in LXD from 6.0 before 6.9, 5.21.0 before 5.21.5, and 5.0.0 before 5.0.7 regarding the handling of project-restriction policies during snapshot restoration.. An authenticated project operator in a restricted multi-tenant environment can bypass policy restrictions by importing a maliciously crafted instance backup containing restricted configuration keys within a snapshot. When the snapshot is restored, these restricted keys are applied to the live instance without policy validation. Starting the modified instance grants the operator unauthorized host root access. |
| OpenProject is open-source, web-based project management software. Prior to 17.3.3 and 17.4.1, the journal diff endpoint discloses hidden historical field values without enforcing object and field visibility. This vulnerability is fixed in 17.3.3 and 17.4.1. |
| A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS). |
| Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. Prior to 2.94.0, the HTML backend has unsafe URI and path handling. This vulnerability is fixed in 2.94.0. |
| Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, Echo's router and static file handler disagree on URL path decoding. The router matches routes using the raw encoded path (preserving %2F as-is), while StaticDirectoryHandler unescapes %2F to / before resolving filesystem paths. This allows an attacker to bypass route-level access controls and read static files without authorization. This vulnerability is fixed in 4.15.3 and 5.2.0. |
| mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.6.4, mise's trust feature gates config files (mise.toml, .tool-versions) through trust_check, but task-include files are loaded on a path that never reaches it. When a directory has a task-include dir (mise-tasks/, .mise/tasks/, …) but no config file, mise falls back to the default includes and renders each task's tera fields — and that tera environment has exec() registered. A {{ exec(command='…') }} in any rendered field runs arbitrary commands the moment the tasks are merely listed. There's no config file to gate on, so no trust prompt ever appears. Read-only commands trigger it: mise tasks, mise task ls, mise run, mise tasks --usage (the query shell completion runs on Tab). The victim only has to cd into a cloned repo and list or tab-complete a task. This vulnerability is fixed in 2026.6.4. |
| Nil-pointer dereference in CreateCustomVolumeFromBackup in LXD up to version 6.8 and 5.21 on Linux allows an authenticated user with can_create_storage_volumes permissions to cause a denial of service via a specially crafted custom-volume backup tarball that omits the expires_at snapshot field. |
| Pagekit CMS 1.0.18 contains a privilege escalation vulnerability that allows authenticated users with the 'user: manage users' permission to escalate privileges by assigning arbitrary custom roles to themselves due to missing authorization checks in UserApiController::saveAction(). Attackers can assign themselves a custom role with the 'system: manage packages' permission and then upload and install a malicious PHP package through the admin package installer to achieve remote code execution. |
| AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to , the `POST /api/integrations/webhooks/{webhook_id}/ping` endpoint fetches the target webhook by primary key alone without verifying that the webhook belongs to the authenticated user. Any authenticated user can supply an arbitrary webhook_id to confirm webhook existence, leak the webhook's OAuth provider type, and in some cases trigger a ping delivery on behalf of another user. This vulnerability is fixed in . |
