| In the Linux kernel, the following vulnerability has been resolved:
ALSA: FCP: do not copy out an uninitialised init response
fcp_ioctl_init() allocates its response buffer with kmalloc() and copies
the whole buffer back to userspace:
buf_size = init.step0_resp_size + init.step2_resp_size;
void *resp __free(kfree) =
kmalloc(buf_size, GFP_KERNEL);
...
if (copy_to_user(arg->resp, resp, buf_size))
return -EFAULT;
Nothing clears the buffer, and the only writer of its leading
step0_resp_size bytes is the step-0 control transfer:
err = snd_usb_ctl_msg(dev, usb_rcvctrlpipe(dev, 0),
FCP_USB_REQ_STEP0,
USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_IN,
0, private->bInterfaceNumber,
step0_resp, private->step0_resp_size);
if (err < 0)
return err;
usb_fill_control_urb() does not set URB_SHORT_NOT_OK, so a short or
zero-length data stage completes with status 0 and snd_usb_ctl_msg()
returns a small actual_length. The only check is err < 0, so a short
transfer is accepted as success.
snd_usb_ctl_msg() copies the full size back unconditionally:
buf = kmemdup(data, size, GFP_KERNEL);
...
memcpy(data, buf, size);
Bytes the device never wrote are therefore restored into resp unchanged
and copied to userspace. step0_resp_size and step2_resp_size are each
validated only to 1..255, so the caller also picks the slab cache, from
kmalloc-8 up to kmalloc-512.
On 7.2.0-rc5 (arm64), device answering step 0 with a zero-length data
stage, s0 = s2 = 255:
# init_on_alloc off, no spray
step0 window [0,255): nonzero=94/255
000: 00 80 60 06 00 00 ff ff 18 00 00 00 57 01 ea 01
010: 08 78 22 13 00 00 ff ff a8 c4 5f 80 00 80 ff ff
# same kernel, kmalloc-512 pre-seeded with an 8-byte tag
step0 window [0,255): nonzero=219/255 tagbytes=232
# identical run, init_on_alloc=1
step0 window [0,255): nonzero=0/255 tagbytes=0
# all three runs
step2 window [255,510): device words matched=62/62
a8 c4 5f 80 00 80 ff ff is the little-endian kernel text address
ffff8000805fc4a8. The step-2 window is unaffected, so the disclosure is
exactly the step-0 region.
Zero the buffer, and require the step-0 transfer to deliver the full
step0_resp_size bytes so a short data stage is reported as an error.

| In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcxhr: initialize mutexes before requesting threaded IRQ
pcxhr_probe() requests pcxhr_threaded_irq() before initializing
mgr->lock, even though the threaded handler takes that mutex.
Initialize the manager locks before request_threaded_irq() so an
early interrupt cannot run against uninitialized mutex state during
probe. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme: target: rdma: fix ndev refcount leak on queue connect
nvmet_rdma_queue_connect() calls nvmet_rdma_find_get_device() which
acquires a reference on the returned ndev via kref_get(). On the path
where the host queue backlog is exceeded and the function returns
NVME_SC_CONNECT_CTRL_BUSY, reference of ndev is not released, leaking
the kref.
Fix this by adding a goto to the existing put_device label before the
early return. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free in smb2_open during durable reconnect
In smb2_open, the call to ksmbd_put_durable_fd(fp) drops the reference
to the durable file descriptor early during the durable reconnect
process. If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails)
or a scavenger accesses the file, it leads to a use-after-free when
accessing fp properties (eg fp->create_time).
Move the single put to the end of the function below err_out2 so fp
stays valid until smb2_open returns. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: ADD_ADDR rtx: free sk if last
When an ADD_ADDR is retransmitted, the sk is held in sk_reset_timer(),
and released at the end.
If at that moment, it was the last reference being held, the sk would
not be freed. sock_put() should then be called instead of __sock_put().
But that's not enough: if it is the last reference, sock_put() will call
sk_free(), which will end up calling sk_stop_timer_sync() on the same
timer, and waiting indefinitely to finish. So it is needed to mark that
the timer is done at the end of the timer handler when it has not been
rescheduled, not to call sk_stop_timer_sync() on "itself". |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: ADD_ADDR rtx: always decrease sk refcount
When an ADD_ADDR is retransmitted, the sk is held in sk_reset_timer().
It should then be released in all cases at the end.
Some (unlikely) checks were returning directly instead of calling
sock_put() to decrease the refcount. Jump to a new 'exit' label to call
__sock_put() (which will become sock_put() in the next commit) to fix
this potential leak.
While at it, drop the '!msk' check which cannot happen because it is
never reset, and explicitly mark the remaining one as "unlikely". |

ext4: move ext4_percpu_param_init() before ext4_mb_init()
When running `kvm-xfstests -c ext4/1k -C 1 generic/383` with the
`DOUBLE_CHECK` macro defined, the following panic is triggered:
==================================================================

This issue can be reproduced using the following commands:
mkfs.ext4 -F -q -b 1024 /dev/sda 5G
tune2fs -O quota,project /dev/sda
mount /dev/sda /tmp/test
With DOUBLE_CHECK defined, mb_group_bb_bitmap_alloc() reads
and validates the block bitmap. When the validation fails,
ext4_mark_group_bitmap_corrupted() attempts to update
sbi->s_freeclusters_counter. However, this percpu_counter has not been
initialized yet at this point, which leads to the panic described above.
Fix this by moving the execution of ext4_percpu_param_init() to occur
before ext4_mb_init(), ensuring the per-CPU counters are initialized
before they are used. |
| In the Linux kernel, the following vulnerability has been resolved:
net: af_key: zero aligned sockaddr tail in PF_KEY exports
PF_KEY export paths use `pfkey_sockaddr_size()` when reserving sockaddr
payload space, so IPv6 addresses occupy 32 bytes on the wire. However,
`pfkey_sockaddr_fill()` initializes only the first 28 bytes of
`struct sockaddr_in6`, leaving the final 4 aligned bytes uninitialized.
Not every PF_KEY message is affected. The state and policy dump builders
already zero the whole message buffer before filling the sockaddr
payloads. Keep the fix to the export paths that still append aligned
sockaddr payloads with plain `skb_put()`:
- `SADB_ACQUIRE`
- `SADB_X_NAT_T_NEW_MAPPING`
- `SADB_X_MIGRATE`
Fix those paths by clearing only the aligned sockaddr tail after
`pfkey_sockaddr_fill()`. |
| A vulnerability has been found in SourceCodester Inventory Management System 1.0. Affected is an unknown function of the file /api/customers_handler.php of the component Customer Management Module. Such manipulation of the argument Customer_Name leads to cross site scripting. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. |
| A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side request forgery (SSRF), making the Dogtag server send HTTP GET requests to internal network services. With the InMemory database backend, the response body of internal targets is disclosed to the attacker through the ACME challenge error. |
| The Auth0 AD/LDAP Connector improperly processes a configuration value during service startup. This allows a low-privileged user on the host system to modify the connector's configuration. When the service restarts, the modified configuration can lead to code execution with the privileges of the service account. |
| The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with custom-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. |
| The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. The etn_manage_event capability is assigned to Contributors by default, meaning any Contributor-level user can set the malicious event_layout value via the REST API without any additional configuration. |
| Improper verification of intent by broadcast receiver in Samsung Cloud Assistant prior to version 9.0.5 allows local attackers to disable enhanced data protection settings. |
| OmniRoute is an open-source AI gateway providing a single endpoint for multiple model providers. In 3.8.49 and earlier, the OmniRoute POST /api/acp/agents custom ACP agent endpoint accepted attacker-controlled binary and versionCommand values and used only a self-consistency check before execFileSync executed the selected interpreter and arguments. The same request called refreshAgentCache, and resolveVersionProbe accepted the matched command before the execFileSync sink ran it. The tokenizeVersionCommand function and DISALLOWED_VERSION_COMMAND_CHARS filter rejected a limited set of shell metacharacters but still allowed interpreter evaluation arguments. The isAuthenticated function relied on isAuthRequired, which accepted anonymous requests when requireLogin was false, while api/acp/ was absent from LOCAL_ONLY_API_PREFIXES and SPAWN_CAPABLE_PREFIXES. With requireLogin=false or during a fresh-instance bootstrap window, a remote anonymous request could supply an interpreter evaluation argument and execute arbitrary code in the server container. With requireLogin=true and a configured management password, exploitation instead required a management session or management-scoped API key. No fixed version is available as of this review. |
| Transmute is a free, open-source, self-hosted file conversion and compression tool. Prior to version 1.3.0, Transmute's URL import endpoint, `POST /api/files/url`, is vulnerable to Server-Side Request Forgery (SSRF). The HTTP downloader used by this endpoint fetches user-supplied URLs with redirects enabled and does not validate whether the target resolves to a public, external address. As a result, an authenticated user (or guest user if they are enabled) may be able to cause the Transmute server to make HTTP requests to internal or cloud-local resources from the server's network position. Because downloaded content is stored and can later be retrieved through `GET /api/files/{id}`, this issue can result in full-read SSRF rather than blind SSRF. This is fixed in version 1.3.0. |
| WeenyGenius, a computer lab management system by Howyar Technologies, has an Origin Validation Error vulnerability. Unauthenticated attackers on the same network can spoof the teacher workstation and send broadcast packets, causing student computers to attempt to establish a connection with the attacker. |
| A Server-Side Request Forgery (SSRF) vulnerability in Google Cloud Gemini Enterprise Agent Platform App Builder versions prior to 2026-06-01 on Google Cloud Platform allows an unauthenticated attacker to leak the Compute Engine default service account access token.
This vulnerability was patched on 01 June 2026. Users will need to redeploy their previously deployed apps. |
| An information leakage vulnerability exists in the Endpoint DLP component (epdlpdrv.sys) of Netskope Client for Windows prior to version R141. An internal communication channel used by the user-space hook DLL to pass messages through the kernel driver to the daemon lacked proper token-based message validation, allowing local unprivileged processes to send unauthorized queries. Additionally, a reply buffer used by the port message handler was not properly initialized before returning data, leaking residual kernel pool memory from prior allocations. A local unprivileged attacker could exploit this vulnerability to enumerate DLP configuration and feature flags, extract live session tokens, and read kernel memory fragments from other users' operations. |
| Server-Side request forgery (SSRF) vulnerability in Yordam Informatics Technology Consulting, Training, and Electronic Systems Industry and Trade Inc. Library Information and Document Automation Program allows Server Side Request Forgery.
This issue affects Library Information and Document Automation Program: before v22.2. |
