https://notcve.org/view.php?id=CVE-2024-26649
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix the null pointer when load rlc firmware If the RLC firmware is invalid because of wrong header size, the pointer to the rlc firmware is released in function amdgpu_ucode_request. There will be a null pointer error in subsequent use. So skip validation to fix it. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu: corrige el puntero nulo al cargar el firmware rlc. Si el firmware RLC no es válido debido a un tamaño de encabezado incorrecto, el puntero al firmware rlc se libera en la función amdgpu_ucode_request. • https://git.kernel.org/stable/c/3da9b71563cbb7281875adab1d7c4132679da987 https://git.kernel.org/stable/c/8b5bacce2d13dbe648f0bfd3f738ecce8db4978c https://git.kernel.org/stable/c/d3887448486caeef9687fb5dfebd4ff91e0f25aa https://git.kernel.org/stable/c/bc03c02cc1991a066b23e69bbcc0f66e8f1f7453 https://access.redhat.com/security/cve/CVE-2024-26649 https://bugzilla.redhat.com/show_bug.cgi?id=2271796 • CWE-476: NULL Pointer Dereference •

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-26646 – thermal: intel: hfi: Add syscore callbacks for system-wide PM
https://notcve.org/view.php?id=CVE-2024-26646
In the Linux kernel, the following vulnerability has been resolved: thermal: intel: hfi: Add syscore callbacks for system-wide PM The kernel allocates a memory buffer and provides its location to the hardware, which uses it to update the HFI table. This allocation occurs during boot and remains constant throughout runtime. When resuming from hibernation, the restore kernel allocates a second memory buffer and reprograms the HFI hardware with the new location as part of a normal boot. The location of the second memory buffer may differ from the one allocated by the image kernel. When the restore kernel transfers control to the image kernel, its HFI buffer becomes invalid, potentially leading to memory corruption if the hardware writes to it (the hardware continues to use the buffer from the restore kernel). It is also possible that the hardware "forgets" the address of the memory buffer when resuming from "deep" suspend. Memory corruption may also occur in such a scenario. To prevent the described memory corruption, disable HFI when preparing to suspend or hibernate. Enable it when resuming. Add syscore callbacks to handle the package of the boot CPU (packages of non-boot CPUs are handled via CPU offline). • https://git.kernel.org/stable/c/28f010dc50df0f7987c04112114fcfa7e0803566 https://git.kernel.org/stable/c/019ccc66d56a696a4dfee3bfa2f04d0a7c3d89ee https://git.kernel.org/stable/c/c9d6d63b6c03afaa6f185df249af693a7939577c https://git.kernel.org/stable/c/97566d09fd02d2ab329774bb89a2cdf2267e86d9 •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2023-52627 – iio: adc: ad7091r: Allow users to configure device events
https://notcve.org/view.php?id=CVE-2023-52627
In the Linux kernel, the following vulnerability has been resolved: iio: adc: ad7091r: Allow users to configure device events AD7091R-5 devices are supported by the ad7091r-5 driver together with the ad7091r-base driver. Those drivers declared iio events for notifying user space when ADC readings fall bellow the thresholds of low limit registers or above the values set in high limit registers. However, to configure iio events and their thresholds, a set of callback functions must be implemented and those were not present until now. The consequence of trying to configure ad7091r-5 events without the proper callback functions was a null pointer dereference in the kernel because the pointers to the callback functions were not set. Implement event configuration callbacks allowing users to read/write event thresholds and enable/disable event generation. Since the event spec structs are generic to AD7091R devices, also move those from the ad7091r-5 driver the base driver so they can be reused when support for ad7091r-2/-4/-8 be added. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: iio: adc: ad7091r: permitir a los usuarios configurar eventos de dispositivo Los dispositivos AD7091R-5 son compatibles con el controlador ad7091r-5 junto con el controlador ad7091r-base. Esos controladores declararon eventos iio para notificar al espacio del usuario cuando las lecturas de ADC caen por debajo de los umbrales de los registros de límite bajo o por encima de los valores establecidos en los registros de límite alto. Sin embargo, para configurar los eventos de iio y sus umbrales, se debe implementar un conjunto de funciones de devolución de llamada que no estaban presentes hasta ahora. • https://git.kernel.org/stable/c/ca69300173b642ba64118200172171ea5967b6c5 https://git.kernel.org/stable/c/1eba6f7ffa295a0eec098c107043074be7cc4ec5 https://git.kernel.org/stable/c/49f322ce1f265935f15e5512da69a399f27a5091 https://git.kernel.org/stable/c/137568aa540a9f587c48ff7d4c51cdba08cfe9a4 https://git.kernel.org/stable/c/89c4e63324e208a23098f7fb15c00487cecbfed2 https://git.kernel.org/stable/c/55aca2ce91a63740278502066beaddbd841af9c6 https://git.kernel.org/stable/c/020e71c7ffc25dfe29ed9be6c2d39af7bd7f661f https://lists.debian.org/debian-lts-announce/2024/06/ •
