| In the Linux kernel, the following vulnerability has been resolved:
NFS: Charge unstable writes by request size, not folio size
nfs_folio_mark_unstable() and nfs_folio_clear_commit() charge and
uncharge NR_WRITEBACK/WB_WRITEBACK by folio_nr_pages(folio) once per
*request* added to or removed from a commit list. This is correct only
when a folio has a single associated request. When pg_test splits a
folio into N sub-folio requests (e.g. pNFS flexfiles striping with a
stripe unit smaller than the folio size, or plain wsize-limited
splitting), each of the N requests independently charges the whole
folio's page count, inflating the accounting by a factor of N per
folio. With large folios and small stripe units this reaches multiple
orders of magnitude: a 2 MiB folio split into 512 4 KiB requests can
charge up to 512x its real size, pushing global dirty+writeback
accounting past the system's dirty threshold and forcing every
buffered writer on the host into the hard-throttle path, including
unrelated in-kernel NFS server threads sharing the box.
Charge each request only for the pages it actually covers. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-esdhc-imx: use pm_runtime_resume_and_get() in suspend
Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() to
simplify error handling. pm_runtime_resume_and_get() automatically
drops the usage counter on failure, avoiding the need for a separate
pm_runtime_put_noidle() call. If it fails, the device is unclocked and
accessing hardware registers would cause a kernel panic, so return the
error immediately. |
| In the Linux kernel, the following vulnerability has been resolved:
llc: fix SAP refcount leak in llc_ui_autobind()
llc_ui_autobind() opens a SAP after choosing a dynamic LSAP.
llc_sap_open() returns a reference owned by the caller, and
llc_sap_add_socket() takes a second reference for the socket's
membership in the SAP hash tables.
llc_ui_bind() drops the caller's reference after adding the socket,
but llc_ui_autobind() keeps it. When the socket is closed,
llc_sap_remove_socket() releases only the socket reference, leaving
the SAP on llc_sap_list with sk_count == 0.
This is user-visible because repeated autobind and close cycles can consume
all dynamic SAP values and make later autobinds fail with -EUSERS.
Drop the caller's reference after a successful autobind, matching
llc_ui_bind()'s ownership model. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: qcom: clear opened when stream enable fails
On enable, subs->opened is set before the service_interval is validated;
an invalid interval jumps to the response label without clearing it, so
the substream is wedged at -EBUSY until a disable or disconnect.
Clear subs->opened on the enable error path. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix refcount leak in nvmet_sq_create()
In nvmet_sq_create(), a reference on the ctrl is taken
via kref_get_unless_zero() before calling nvmet_check_sqid().
If nvmet_check_sqid() fails, the function returns the error
directly without releasing the reference, leading to a leak.
Fix this by jumping to the "ctrl_put" label, which already
performs the necessary nvmet_ctrl_put(ctrl). This ensures the
reference is properly released on this error path. |
| In the Linux kernel, the following vulnerability has been resolved:
net: fib_rules: Don't dump dying fib_rule in fib_rules_dump().
rocker_router_fib_event() calls fib_rule_get() during RCU dump.
If the fib_rule is dying, refcount_inc() will complain about it.
Let's call refcount_inc_not_zero() in fib_rules_dump(). |
| In the Linux kernel, the following vulnerability has been resolved:
mlxsw: fix refcount leak in mlxsw_sp_vrs_lpm_tree_replace()
When mlxsw_sp_vrs_lpm_tree_replace() fails after replacing some VRs,
the error rollback loop does not correctly revert the preceding
replacements. The loop decrements the index but fails to update the
vr pointer, which still points to the VR that caused the failure. As
a result, the condition and the rollback call always operate on the
same VR, potentially calling mlxsw_sp_vr_lpm_tree_replace() multiple
times on it while never rolling back the earlier VRs. Those VRs
continue to hold a reference to new_tree acquired via
mlxsw_sp_lpm_tree_hold(), leaking the reference count of new_tree.
Fix by reinitializing vr inside the error loop with the updated index:
vr = &mlxsw_sp->router->vrs[i];
so that the loop correctly iterates over all VRs that were actually
replaced. |
| Gitea prior to 1.27.0 contains a server-side request forgery vulnerability that allows authenticated attackers to bypass SSRF protections by exploiting HTTP fetch operations in migration and OAuth avatar code paths that use Go's default http.Get without a custom DialContext. Attackers can supply arbitrary URLs through release asset download URLs, pull-request patch URLs, or OAuth avatar endpoints to reach internal services, cloud instance-metadata endpoints, or read local files such as the application configuration containing database credentials and signing secrets, with exfiltrated content persisted as migration release assets for later retrieval. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: fix TIME_WAIT socket reference leak on PSP policy failure
Release the TIME_WAIT socket reference and jump to discard_it
upon PSP policy failure in both IPv4 and IPv6 receive paths.
This prevents a memory leak of tcp_tw_bucket structures. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/imagination: Fix double call to drm_sched_entity_fini()
Call sequence of double call:
pvr_context_destroy
pvr_context_kill_queues
pvr_queue_kill
drm_sched_entity_destroy
drm_sched_entity_fini // here
pvr_context_put
kref_put(..., pvr_context_release)
pvr_context_destroy_queues
pvr_queue_destroy
drm_sched_entity_fini // here
Call to drm_sched_entity_destroy() from pvr_context_kill_queues() calls
drm_sched_entity_flush() + drm_sched_entity_fini().
drm_sched_entity_flush() ensures all pending jobs are completed and
drm_sched_entity_fini() ensures no further submission is allowed as
per expectation from pvr_context_kill_queues(). Double call to
drm_sched_entity_fini() is misuse of the API so keep call only in
pvr_context_create() failure path.

| Axios is a promise based HTTP client for the browser and Node.js. Versions prior to 1.15.0 and 0.3.1 are vulnerable to a specific gadget-style attack chain in which prototype pollution in a third-party dependency may be leveraged to inject unsanitized header values into outbound requests. This vulnerability is fixed in 1.15.0 and 0.3.1. |
| A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to access hidden commands. The vulnerability is due to the presence of undocumented configuration commands. An attacker could exploit this vulnerability by performing specific steps that make the hidden commands accessible. A successful exploit could allow the attacker to make configuration changes to various sections of an affected device that should not be exposed to CLI access. |
| In the Linux kernel, the following vulnerability has been resolved:
ovpn: fix peer refcount leak in TCP error paths
When either the TCP RX or TX error path calls ovpn_peer_hold() followed
by schedule_work(&peer->tcp.defer_del_work), and the work item is already
pending from the other path, schedule_work() returns false and the work
runs only once. Since ovpn_tcp_peer_del_work() calls ovpn_peer_put()
exactly once, the extra reference taken by the losing path is never
dropped, leaking the peer object.
The race window:
CPU0 (strparser/RX error): CPU1 (tcp_tx_work/TX error):
ovpn_peer_hold() <- refcnt+1 ovpn_peer_hold() <- refcnt+2
schedule_work() <- queued schedule_work() <- NO-OP
(work already pending)
ovpn_tcp_peer_del_work runs:
ovpn_peer_del()
ovpn_peer_put() <- refcnt+1
<- peer never freed
Fix by checking the return value of schedule_work() in both paths and
calling ovpn_peer_put() to drop the extra reference if the work was
already pending. ovpn_peer_hold() is kept unconditional in the TX path
as it cannot fail at that point. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gpusvm: Fix MM reference leak in drm_gpusvm_range_evict
If kvmalloc_array() fails in drm_gpusvm_range_evict(), the MM
reference acquired earlier is not released, resulting in a reference
leak.
Fix this by dropping the MM reference on the kvmalloc_array()
failure path. |
| Microsoft Exchange Server Remote Code Execution Vulnerability |
| Ground Station prior to 0.6.0 contains an unauthenticated blind server-side request forgery vulnerability in the orbital-source configuration path that allows any unauthenticated Socket.IO client to cause the ground-station process to issue outbound HTTP requests to attacker-chosen destinations. Attackers can connect to the Socket.IO server on port 7000 without credentials due to disabled authentication enforcement and a wildcard CORS policy, then submit a data_submission event with submit-orbital-sources action to persist an attacker-supplied URL in the database, then trigger an orbital sync via the equally unauthenticated background_task:start event. The URL is stored with no scheme allowlist, no host validation, and no rejection of loopback, RFC1918, or link-local (cloud instance metadata at 169.254.169.254) addresses, and is passed directly to requests.get in _fetch_http_3le and _fetch_http_omm in backend/tlesync/source_adapters.py. HTTP status codes and error messages from the outbound request are emitted in the orbital_sync_state Socket.IO event to all connected clients, providing a serviceable oracle for interpreting internal-service and cloud-metadata responses even though the raw response body is not directly leaked. Because the malicious source persists in the database across restarts and re-fires every 24 hours on the scheduled sync cycle, the primitive gives durable long-term SSRF without the attacker needing to remain connected. |
| Odysseus before commit 87babb5 contains a server-side request forgery vulnerability that allows admin-privileged attackers to direct the server to probe internal network resources by supplying arbitrary URLs to the embedding endpoint configuration without scheme, host, IP range, or DNS rebind validation. Attackers can submit loopback addresses, RFC 1918 ranges, or link-local addresses through the embedding endpoint API to partially read responses from cloud instance metadata services, internal APIs, and other hosts reachable from the server. |
| Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a
rewrites() or redirects() rule that builds its external destination hostname from request-controlled input can be pointed at an arbitrary hostname, regardless of the rule's hostname suffix. For a rewrite, Next.js proxies the request to that arbitrary host and serves the response from the application's origin, leading to Server-Side Request forgery. A redirects() rule configured this way is vulnerable to an Open Redirect. This issue has been fixed in versions 15.5.21 and 16.2.11. |
| MaxKB before 2.10.0 contains a server-side request forgery vulnerability in tool creation and update endpoints that allows authenticated users to make arbitrary server requests by supplying unvalidated downloadCallbackUrl and download_url parameters. Attackers with default workspace USER role can exploit this to access internal network services by providing malicious URLs to the ToolSerializer endpoints. |
| Nanobot prior to version 0.2.1 contains a server-side request forgery vulnerability in the Microsoft Teams channel handler that allows remote attackers to exfiltrate Bot Framework bearer tokens by supplying a forged activity with an attacker-controlled serviceUrl value. Attackers can poison the stored conversation reference by sending a crafted inbound activity to the Teams webhook, causing subsequent bot replies to transmit token-bearing Authorization header requests to an attacker-controlled host. |
