| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()
KSAN reports use-after-free in hci_add_adv_monitor().
While adding an adv monitor,
hci_add_adv_monitor() calls ->
msft_add_monitor_pattern() calls ->
msft_add_monitor_sync() calls ->
msft_le_monitor_advertisement_cb() calls in an error case ->
hci_free_adv_monitor() which frees the *moniter.
This is referenced by bt_dev_dbg() in hci_add_adv_monitor().
Fix the bt_dev_dbg() by using handle instead of monitor->handle. |
| Cross site request forgery in Kiteworks OwnCloud allows an unauthenticated attacker to forge requests.
If a request has no Authorization header, it is created with an empty string as value by a rewrite rule. The CSRF check is done by comparing the header value to null, meaning that the existing CSRF check is bypassed in this case. An attacker can, for example, create a new administrator account if the request is executed in the browser of an authenticated victim. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix null-ptr-deref in raid10_sync_request
init_resync() inits mempool and sets conf->have_replacemnt at the beginning
of sync, close_sync() frees the mempool when sync is completed.
After [1] recovery might be skipped and init_resync() is called but
close_sync() is not. null-ptr-deref occurs with r10bio->dev[i].repl_bio.
The following is one way to reproduce the issue.
1) create a array, wait for resync to complete, mddev->recovery_cp is set
to MaxSector.
2) recovery is woken and it is skipped. conf->have_replacement is set to
0 in init_resync(). close_sync() not called.
3) some io errors and rdev A is set to WantReplacement.
4) a new device is added and set to A's replacement.
5) recovery is woken, A have replacement, but conf->have_replacemnt is
0. r10bio->dev[i].repl_bio will not be alloced and null-ptr-deref
occurs.
Fix it by not calling init_resync() if recovery skipped.

| In the Linux kernel, the following vulnerability has been resolved:
usb: early: xhci-dbc: Fix a potential out-of-bound memory access
If xdbc_bulk_write() fails, the values in 'buf' can be anything. So the
string is not guaranteed to be NULL terminated when xdbc_trace() is called.
Reserve an extra byte, which will be zeroed automatically because 'buf' is
a static variable, in order to avoid troubles, should it happen. |

ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove
The MBHC resources must be released on component probe failure and
removal so can not be tied to the lifetime of the component device.
This is specifically needed to allow probe deferrals of the sound card
which otherwise fails when reprobing the codec component:
snd-sc8280xp sound: ASoC: failed to instantiate card -517
genirq: Flags mismatch irq 299. 00002001 (mbhc sw intr) vs. 00002001 (mbhc sw intr)

| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix infinite loop in nilfs_mdt_get_block()
If the disk image that nilfs2 mounts is corrupted and a virtual block
address obtained by block lookup for a metadata file is invalid,
nilfs_bmap_lookup_at_level() may return the same internal return code as
-ENOENT, meaning the block does not exist in the metadata file.
This duplication of return codes confuses nilfs_mdt_get_block(), causing
it to read and create a metadata block indefinitely.
In particular, if this happens to the inode metadata file, ifile,
semaphore i_rwsem can be left held, causing task hangs in lock_mount.
Fix this issue by making nilfs_bmap_lookup_at_level() treat virtual block
address translation failures with -ENOENT as metadata corruption instead
of returning the error code. |

usb-storage: alauda: Fix uninit-value in alauda_check_media()
Syzbot got KMSAN to complain about access to an uninitialized value in
the alauda subdriver of usb-storage:
BUG: KMSAN: uninit-value in alauda_transport+0x462/0x57f0
drivers/usb/storage/alauda.c:1137
CPU: 0 PID: 12279 Comm: usb-storage Not tainted 5.3.0-rc7+ #0

alauda_check_media+0x344/0x3310 drivers/usb/storage/alauda.c:460
The problem is that alauda_check_media() doesn't verify that its USB
transfer succeeded before trying to use the received data. What
should happen if the transfer fails isn't entirely clear, but a
reasonably conservative approach is to pretend that no media is
present.
A similar problem exists in a usb_stor_dbg() call in
alauda_get_media_status(). In this case, when an error occurs the
call is redundant, because usb_stor_ctrl_transfer() already will print
a debugging message.
Finally, unrelated to the uninitialized memory access, is the fact
that alauda_check_media() performs DMA to a buffer on the stack.
Fortunately usb-storage provides a general purpose DMA-able buffer for
uses like this. We'll use it instead. |
| In the Linux kernel, the following vulnerability has been resolved:
iavf: use internal state to free traffic IRQs
If the system tries to close the netdev while iavf_reset_task() is
running, __LINK_STATE_START will be cleared and netif_running() will
return false in iavf_reinit_interrupt_scheme(). This will result in
iavf_free_traffic_irqs() not being called and a leak as follows:
[7632.489326] remove_proc_entry: removing non-empty directory 'irq/999', leaking at least 'iavf-enp24s0f0v0-TxRx-0'

is shown when pci_disable_msix() is later called. Fix by using the
internal adapter state. The traffic IRQs will always exist if
state == __IAVF_RUNNING. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dp: Drop aux devices together with DP controller
Using devres to depopulate the aux bus made sure that upon a probe
deferral the EDP panel device would be destroyed and recreated upon next
attempt.
But the struct device which the devres is tied to is the DPUs
(drm_dev->dev), which may be happen after the DP controller is torn
down.
Indications of this can be seen in the commonly seen EDID-hexdump full
of zeros in the log, or the occasional/rare KASAN fault where the
panel's attempt to read the EDID information causes a use after free on
DP resources.
It's tempting to move the devres to the DP controller's struct device,
but the resources used by the device(s) on the aux bus are explicitly
torn down in the error path. The KASAN-reported use-after-free also
remains, as the DP aux "module" explicitly frees its devres-allocated
memory in this code path.
As such, explicitly depopulate the aux bus in the error path, and in the
component unbind path, to avoid these issues.

| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8186: Fix use-after-free in driver remove path
When devm runs function in the "remove" path for a device it runs them
in the reverse order. That means that if you have parts of your driver
that aren't using devm or are using "roll your own" devm w/
devm_add_action_or_reset() you need to keep that in mind.
The mt8186 audio driver didn't quite get this right. Specifically, in
mt8186_init_clock() it called mt8186_audsys_clk_register() and then
went on to call a bunch of other devm function. The caller of
mt8186_init_clock() used devm_add_action_or_reset() to call
mt8186_deinit_clock() but, because of the intervening devm functions,
the order was wrong.
Specifically at probe time, the order was:
1. mt8186_audsys_clk_register()
2. afe_priv->clk = devm_kcalloc(...)
3. afe_priv->clk[i] = devm_clk_get(...)
At remove time, the order (which should have been 3, 2, 1) was:
1. mt8186_audsys_clk_unregister()
3. Free all of afe_priv->clk[i]
2. Free afe_priv->clk
The above seemed to be causing a use-after-free. Luckily, it's easy to
fix this by simply using devm more correctly. Let's move the
devm_add_action_or_reset() to the right place. In addition to fixing
the use-after-free, code inspection shows that this fixes a leak
(missing call to mt8186_audsys_clk_unregister()) that would have
happened if any of the syscon_regmap_lookup_by_phandle() calls in
mt8186_init_clock() had failed. |

This was somewhat not so easy to spot, because "ocelot-8021q" is not the
default tagging protocol, and thus, not everyone who tests the unbinding
path may have switched to it beforehand. The default
felix_tag_npi_teardown() does not require rtnl_lock() to be held. |

| The MainWP Child – Securely Connects to the MainWP Dashboard to Manage Multiple Sites plugin for WordPress is vulnerable to privilege escalation due to a missing authorization checks on the register_site function in all versions up to, and including, 5.2 when a site is left in an unconfigured state. This makes it possible for unauthenticated attackers to log in as an administrator on instances where MainWP Child is not yet connected to the MainWP Dashboard. IMPORTANT: this only affects sites who have MainWP Child installed and have not yet connected to the MainWP Dashboard, and do not have the unique security ID feature enabled. Sites already connected to the MainWP Dashboard plugin and do not have the unique security ID feature enabled, are NOT affected and not required to upgrade. Please note versions up to 5.3.3 contained a patch, though a bypass was discovered and not addressed until version 5.3.4. |
| It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources processing the queries. Zones will usually need to have been deliberately crafted to attack this exposure.
This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.32-S1. |
| The WP Timetics- AI-powered Appointment Booking Calendar and Online Scheduling Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the /wp-json/timetics/v1/customers/ REST API endpoint in all versions up to, and including, 1.0.27. This makes it possible for authenticated attackers, with Timetics Customer access and above, to delete arbitrary users. |
| The Primer MyData for Woocommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'img_src' parameter in all versions up to, and including, 4.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. |
| Improper verification of the digital signature in ksojscore.dll in Kingsoft WPS Office in versions equal or less than 12.1.0.18276
on Windows allows an attacker to load an arbitrary Windows library. The patch released in version 12.2.0.16909 to mitigate CVE-2024-7262 was not restrictive enough. |
| Using API in the 2N OS device, authorized user can enable logging, which discloses valid authentication tokens in system log.
