Vulnerabilities

A vulnerability was found in Tenda AC7 15.03.06.44. It has been rated as critical. This issue affects the function formWifiWpsStart of the file /goform/WifiWpsStart. The manipulation of the argument index leads to stack-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-257939. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Fix variable deferencing before NULL check in edp_setup_replay()<br /> <br /> In edp_setup_replay(), &amp;#39;struct dc *dc&amp;#39; &amp; &amp;#39;struct dmub_replay *replay&amp;#39;<br /> was dereferenced before the pointer &amp;#39;link&amp;#39; &amp; &amp;#39;replay&amp;#39; NULL check.<br /> <br /> Fixes the below:<br /> drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:947 edp_setup_replay() warn: variable dereferenced before check &amp;#39;link&amp;#39; (see line 933)

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amdgpu: Fix the null pointer when load rlc firmware<br /> <br /> If the RLC firmware is invalid because of wrong header size,<br /> the pointer to the rlc firmware is released in function<br /> amdgpu_ucode_request. There will be a null pointer error<br /> in subsequent use. So skip validation to fix it.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

A vulnerability was found in Tenda AC7 15.03.06.44. It has been declared as critical. This vulnerability affects the function formWifiWpsOOB of the file /goform/WifiWpsOOB. The manipulation of the argument index leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-257938 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> thermal: intel: hfi: Add syscore callbacks for system-wide PM<br /> <br /> The kernel allocates a memory buffer and provides its location to the<br /> hardware, which uses it to update the HFI table. This allocation occurs<br /> during boot and remains constant throughout runtime.<br /> <br /> When resuming from hibernation, the restore kernel allocates a second<br /> memory buffer and reprograms the HFI hardware with the new location as<br /> part of a normal boot. The location of the second memory buffer may<br /> differ from the one allocated by the image kernel.<br /> <br /> When the restore kernel transfers control to the image kernel, its HFI<br /> buffer becomes invalid, potentially leading to memory corruption if the<br /> hardware writes to it (the hardware continues to use the buffer from the<br /> restore kernel).<br /> <br /> It is also possible that the hardware "forgets" the address of the memory<br /> buffer when resuming from "deep" suspend. Memory corruption may also occur<br /> in such a scenario.<br /> <br /> To prevent the described memory corruption, disable HFI when preparing to<br /> suspend or hibernate. Enable it when resuming.<br /> <br /> Add syscore callbacks to handle the package of the boot CPU (packages of<br /> non-boot CPUs are handled via CPU offline). Syscore ops always run on the<br /> boot CPU. Additionally, HFI only needs to be disabled during "deep" suspend<br /> and hibernation. Syscore ops only run in these cases.<br /> <br /> [ rjw: Comment adjustment, subject and changelog edits ]

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Refactor DMCUB enter/exit idle interface<br /> <br /> [Why]<br /> We can hang in place trying to send commands when the DMCUB isn&amp;#39;t<br /> powered on.<br /> <br /> [How]<br /> We need to exit out of the idle state prior to sending a command,<br /> but the process that performs the exit also invokes a command itself.<br /> <br /> Fixing this issue involves the following:<br /> <br /> 1. Using a software state to track whether or not we need to start<br /> the process to exit idle or notify idle.<br /> <br /> It&amp;#39;s possible for the hardware to have exited an idle state without<br /> driver knowledge, but entering one is always restricted to a driver<br /> allow - which makes the SW state vs HW state mismatch issue purely one<br /> of optimization, which should seldomly be hit, if at all.<br /> <br /> 2. Refactor any instances of exit/notify idle to use a single wrapper<br /> that maintains this SW state.<br /> <br /> This works simialr to dc_allow_idle_optimizations, but works at the<br /> DMCUB level and makes sure the state is marked prior to any notify/exit<br /> idle so we don&amp;#39;t enter an infinite loop.<br /> <br /> 3. Make sure we exit out of idle prior to sending any commands or<br /> waiting for DMCUB idle.<br /> <br /> This patch takes care of 1/2. A future patch will take care of wrapping<br /> DMCUB command submission with calls to this new interface.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5e: Fix operation precedence bug in port timestamping napi_poll context<br /> <br /> Indirection (*) is of lower precedence than postfix increment (++). Logic<br /> in napi_poll context would cause an out-of-bound read by first increment<br /> the pointer address by byte address space and then dereference the value.<br /> Rather, the intended logic was to dereference first and then increment the<br /> underlying value.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: adc: ad7091r: Allow users to configure device events<br /> <br /> AD7091R-5 devices are supported by the ad7091r-5 driver together with<br /> the ad7091r-base driver. Those drivers declared iio events for notifying<br /> user space when ADC readings fall bellow the thresholds of low limit<br /> registers or above the values set in high limit registers.<br /> However, to configure iio events and their thresholds, a set of callback<br /> functions must be implemented and those were not present until now.<br /> The consequence of trying to configure ad7091r-5 events without the<br /> proper callback functions was a null pointer dereference in the kernel<br /> because the pointers to the callback functions were not set.<br /> <br /> Implement event configuration callbacks allowing users to read/write<br /> event thresholds and enable/disable event generation.<br /> <br /> Since the event spec structs are generic to AD7091R devices, also move<br /> those from the ad7091r-5 driver the base driver so they can be reused<br /> when support for ad7091r-2/-4/-8 be added.

It is possible for a user in a different organization from the owner of a snapshot to bypass authorization and delete a snapshot by issuing a DELETE request to /api/snapshots/ using its view key. This functionality is intended to only be available to individuals with the permission to write/edit to the snapshot in question, but due to a bug in the authorization logic, deletion requests issued by an unprivileged user in a different organization than the snapshot owner are treated as authorized.<br /> <br /> Grafana Labs would like to thank Ravid Mazon and Jay Chen of Palo <br /> Alto Research for discovering and disclosing this vulnerability.<br /> <br /> This issue affects Grafana: from 9.5.0 before 9.5.18, from 10.0.0 before 10.0.13, from 10.1.0 before 10.1.9, from 10.2.0 before 10.2.6, from 10.3.0 before 10.3.5.
