Description: Impact
A vulnerability in the Backstage permission plugin backend allows callers to extract some information about the conditional decisions returned by the permission policy installed in the permission backend. If the permission system is not in use or if the installed permission policy does not use conditional decisions, there is no impact.
Patches
This issue has been resolved in version 0.6.0 of the permissions backend.
Workarounds
Administrators of the permission policies can ensure that they are crafted in such a way that conditional decisions do not contain any sensitive information.

Description: Impact
This vulnerability impacts users of a subwiki of XWiki where Message Stream is enabled and use, if they configured their wiki to be closed by selecting "Prevent unregistered users to view pages" in the Administrations Rights.
The vulnerability is that any message sent in a subwiki to "everyone" is actually sent to the farm: any visitor of the main wiki will be able to see that message through the Dashboard, even if the subwiki is configured to be private.
Patches
This problem has not been patched and is not going to be patched in the future: Message Stream has been deprecated in XWiki 16.8.0RC1 and is not maintained anymore.
Workarounds
Message Stream is disabled by default, it's advised to keep it disabled from Administration > Social > Message Stream.

CVE-2025-20178 |
Description:
A vulnerability in the web-based management interface of Cisco Secure Network Analytics could allow an authenticated, remote attacker with valid administrative credentials to execute arbitrary commands as root on the underlying operating system.
This vulnerability is due to insufficient integrity checks within device backup files. An attacker with valid administrative credentials could exploit this vulnerability by crafting a malicious backup file and restoring it to an affected device. A successful exploit could allow the attacker to obtain shell access on the underlying operating system with the privileges of root.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVE-2025-20236 |
Description:
A vulnerability in the custom URL parser of Cisco Webex App could allow an unauthenticated, remote attacker to persuade a user to download arbitrary files, which could allow the attacker to execute arbitrary commands on the host of the targeted user.
This vulnerability is due to insufficient input validation when Cisco Webex App processes a meeting invite link. An attacker could exploit this vulnerability by persuading a user to click a crafted meeting invite link and download arbitrary files. A successful exploit could allow the attacker to execute arbitrary commands with the privileges of the targeted user.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVE-2025-20150 |
Description:
A vulnerability in Cisco Nexus Dashboard could allow an unauthenticated, remote attacker to enumerate LDAP user accounts.
This vulnerability is due to the improper handling of LDAP authentication requests. An attacker could exploit this vulnerability by sending authentication requests to an affected system. A successful exploit could allow an attacker to determine which usernames are valid LDAP user accounts.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVE-2025-23138 |
Description: In the Linux kernel, the following vulnerability has been resolved:
watch_queue: fix pipe accounting mismatch
Currently, watch_queue_set_size() modifies the pipe buffers charged to
user->pipe_bufs without updating the pipe->nr_accounted on the pipe
itself, due to the if (!pipe_has_watch_queue()) test in
pipe_resize_ring(). This means that when the pipe is ultimately freed,
we decrement user->pipe_bufs by something other than what than we had
charged to it, potentially leading to an underflow. This in turn can
cause subsequent too_many_pipe_buffers_soft() tests to fail with -EPERM.
To remedy this, explicitly account for the pipe usage in
watch_queue_set_size() to match the number set via account_pipe_buffers()
(It's unclear why watch_queue_set_size() does not update nr_accounted;
it may be due to intentional overprovisioning in watch_queue_set_size()?)

CVE-2025-23137 |

CVE-2025-23136 |
Description: In the Linux kernel, the following vulnerability has been resolved:
thermal: int340x: Add NULL check for adev
Not all devices have an ACPI companion fwnode, so adev might be NULL.
This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").
Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in int3402_thermal_probe().
Note, under the same directory, int3400_thermal_probe() has such a
check.

CVE-2025-23135 |
Description: In the Linux kernel, the following vulnerability has been resolved:
RISC-V: KVM: Teardown riscv specific bits after kvm_exit
During a module removal, kvm_exit invokes arch specific disable
call which disables AIA. However, we invoke aia_exit before kvm_exit
resulting in the following warning. KVM kernel module can't be inserted
afterwards due to inconsistent state of IRQ.
