| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: prevent uninitialized lcn caused by zero len
syzbot reported a uninit-value in ntfs_iomap_begin [1].
Since runs was not touched yet, run_lookup_entry() immediately fails
and returns false, which makes the value of "*len" 0.
Simultaneously, the new value and err value are also 0, causing the
logic in attr_data_get_block_locked() to jump directly to ok, ultimately
resulting in *lcn being triggered before it is set [1].
In ntfs_iomap_begin(), the check for a 0 value in clen is moved forward
to before updating lcn to avoid this [1].

| In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix af_unix null-ptr-deref in proto update
unix_stream_connect() sets sk_state (`WRITE_ONCE(sk->sk_state,
TCP_ESTABLISHED)`) _before_ it assigns a peer (`unix_peer(sk) = newsk`).
sk_state == TCP_ESTABLISHED makes sock_map_sk_state_allowed() believe that
socket is properly set up, which would include having a defined peer. IOW,
there's a window when unix_stream_bpf_update_proto() can be called on
socket which still has unix_peer(sk) == NULL.

BUG: kernel NULL pointer dereference, address: 0000000000000080

Initial idea was to move peer assignment _before_ the sk_state update[1],
but that involved an additional memory barrier, and changing the hot path
was rejected.
Then a NULL check during proto update in unix_stream_bpf_update_proto() was
considered[2], but the follow-up discussion[3] focused on the root cause,
i.e. sockmap update taking a wrong lock. Or, more specifically, missing
unix_state_lock()[4].
In the end it was concluded that teaching sockmap about the af_unix locking
would be unnecessarily complex[5].
Complexity aside, since BPF_PROG_TYPE_SCHED_CLS and BPF_PROG_TYPE_SCHED_ACT
are allowed to update sockmaps, sock_map_update_elem() taking the unix
lock, as it is currently implemented in unix_state_lock():
spin_lock(&unix_sk(s)->lock), would be problematic. unix_state_lock() taken
in a process context, followed by a softirq-context TC BPF program
attempting to take the same spinlock -- deadlock[6].
This way we circled back to the peer check idea[2].

Summary of scenarios where af_unix/stream connect() may race a sockmap
update:
1. connect() vs. bpf(BPF_MAP_UPDATE_ELEM), i.e. sock_map_update_elem_sys()
Implemented NULL check is sufficient. Once assigned, socket peer won't
be released until socket fd is released. And that's not an issue because
sock_map_update_elem_sys() bumps fd refcnf.
2. connect() vs BPF program doing update
Update restricted per verifier.c:may_update_sockmap() to
BPF_PROG_TYPE_TRACING/BPF_TRACE_ITER
BPF_PROG_TYPE_SOCK_OPS (bpf_sock_map_update() only)

Seems like the TPM chip supports sha3_256, which isn't yet in
tpm_algorithms:
tpm tpm0: TPM with unsupported bank algorithm 0x0027
That's TPM_ALG_SHA3_256 == 0x0027 from "Trusted Platform Module 2.0
Library Part 2: Structures", page 51 [1].
See also the related U-Boot algorithms update [2].
Thus solve the problem by creating a file name with "_tpm_alg_<ID>"
postfix if the crypto algorithm isn't initialized.

| A Stored Cross-Site Scripting (XSS) vulnerability exists in Frappe Framework version 17.0.0-dev due to improper neutralization of user-controlled input in the Desk desktop icon renderer. |
| The Generate Security.txt plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.12. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete the site's security.txt file from the server filesystem or create the .well-known directory by directly invoking the delete_securitytxt or create_wellknown_folder AJAX actions. |
| The Kargo Takip plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.2 via the 'api_url' parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. The script echoes internal API response data (specifically the value of any 'auth' key in a JSON response body) verbatim back to the attacker's browser, enabling direct exfiltration of responses from internal services such as cloud instance metadata endpoints. |
| The Secufor_OAuth plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 1.0.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to disconnect the WordPress site from its linked Secufor account by clearing the plugin's stored login token and user login configuration. |
| The Devs Accounting – Simple Accounting and Invoicing Solution plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.2.0. This is due to the get_single_account() REST API callback being registered with a permission_callback that unconditionally returns true, providing no authentication or authorization checks on the /devs-accounting/v1/get-account/<id> endpoint. This makes it possible for unauthenticated attackers to read arbitrary private financial account records (including account name, bank name, and opening balance) by enumerating the numeric account ID, resulting in sensitive information disclosure. |
| The Email JavaScript Cloak plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'email' shortcode in all versions up to, and including, 1.03 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, an authenticated user with columnAdd permission on a Postgres-backed base can inject arbitrary SQL into the formula engine via the optional direction argument of ARRAYSORT(...). The value is unrestricted by formula validation and embedded into a knex.raw ORDER BY clause, executing during column creation and on every subsequent record read of the formula column. The vulnerability is specific to the Postgres mapping for ARRAYSORT in packages/nocodb/src/db/functionMappings/pg.ts. This vulnerability is fixed in 2026.04.1. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free from async crypto on Qualcomm crypto engine
ksmbd_crypt_message() sets a NULL completion callback on AEAD requests
and does not handle the -EINPROGRESS return code from async hardware
crypto engines like the Qualcomm Crypto Engine (QCE). When QCE returns
-EINPROGRESS, ksmbd treats it as an error and immediately frees the
request while the hardware DMA operation is still in flight. The DMA
completion callback then dereferences freed memory, causing a NULL
pointer crash:
pc : qce_skcipher_done+0x24/0x174
lr : vchan_complete+0x230/0x27c
...
el1h_64_irq+0x68/0x6c
ksmbd_free_work_struct+0x20/0x118 [ksmbd]
ksmbd_exit_file_cache+0x694/0xa4c [ksmbd]
Use the standard crypto_wait_req() pattern with crypto_req_done() as
the completion callback, matching the approach used by the SMB client
in fs/smb/client/smb2ops.c. This properly handles both synchronous
engines (immediate return) and async engines (-EINPROGRESS followed
by callback notification). |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: prevent NULL pointer dereference during unmount
When flushing out outstanding glock work during an unmount, gfs2_log_flush()
can be called when sdp->sd_jdesc has already been deallocated and sdp->sd_jdesc
is NULL. Commit 35264909e9d1 ("gfs2: Fix NULL pointer dereference in
gfs2_log_flush") added a check for that to gfs2_log_flush() itself, but it
missed the sdp->sd_jdesc dereference in gfs2_log_release(). Fix that. |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: add some missing log locking
Function gfs2_logd() calls the log flushing functions gfs2_ail1_start(),
gfs2_ail1_wait(), and gfs2_ail1_empty() without holding sdp->sd_log_flush_lock,
but these functions require exclusion against concurrent transactions.
To fix that, add a non-locking __gfs2_log_flush() function. Then, in
gfs2_logd(), take sdp->sd_log_flush_lock before calling the above mentioned log
flushing functions and __gfs2_log_flush(). |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: qcom: qdsp6: topology: check widget type before accessing data
Check widget type before accessing the private data, as this could a
virtual widget which is no associated with a dsp graph, container and
module. Accessing witout check could lead to incorrect memory access. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/sec2 - prevent req used-after-free for sec
During packet transmission, if the system is under heavy load,
the hardware might complete processing the packet and free the
request memory (req) before the transmission function finishes.
If the software subsequently accesses this req, a use-after-free
error will occur. The qp_ctx memory exists throughout the packet
sending process, so replace the req with the qp_ctx. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: fix mismatch between power and frequency
During DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops
the MMCX rail to MIN_SVS while the core clock frequency remains at its
original (highest) rate. When runtime resume re-enables the clock, this
may result in a mismatch between the rail voltage and the clock rate.
For example, in the DPU bind path, the sequence could be:
cpu0: dev_sync_state -> rpmhpd_sync_state
cpu1: dpu_kms_hw_init
timeline 0 ------------------------------------------------> t
After rpmhpd_sync_state, the voltage performance is no longer guaranteed
to stay at the highest level. During dpu_kms_hw_init, calling
dev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to
fall to MIN_SVS while the core clock is still at its maximum frequency.
When the power is re-enabled, only the clock is enabled, leading to a
situation where the MMCX rail is at MIN_SVS but the core clock is at its
highest rate. In this state, the rail cannot sustain the clock rate,
which may cause instability or system crash.
Remove the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend
to ensure the correct vote is restored when DPU resumes.
