CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52693 – ACPI: video: check for error while searching for backlight device parent
https://notcve.org/view.php?id=CVE-2023-52693
In the Linux kernel, the following vulnerability has been resolved: ACPI: video: check for error while searching for backlight device parent If acpi_get_parent() called in acpi_video_dev_register_backlight() fails, for example, because acpi_ut_acquire_mutex() fails inside acpi_get_parent), this can lead to incorrect (uninitialized) acpi_parent handle being passed to acpi_get_pci_dev() for detecting the parent pci device. Check acpi_get_parent() result and set parent device only in case of success. Found by Linux Verification Center (linuxtesting.org) with SVACE. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPI: vídeo: comprueba si hay errores al buscar el dispositivo de retroiluminación principal. Si la llamada acpi_get_parent() en acpi_video_dev_register_backlight() fallo, por ejemplo, porque acpi_ut_acquire_mutex() fallo dentro de acpi_get_parent), esto puede provocar que se pase el identificador acpi_parent incorrecto (no inicializado) a acpi_get_pci_dev() para detectar el dispositivo pci principal. Verifique el resultado de acpi_get_parent() y configure el dispositivo principal solo en caso de éxito.

In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: Add missing error check to scarlett2_usb_set_config() scarlett2_usb_set_config() calls scarlett2_usb_get() but was not checking the result. Return the error if it fails rather than continuing with an invalid value. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ALSA: scarlett2: Añadida verificación de error faltante a scarlett2_usb_set_config() scarlett2_usb_set_config() llama a scarlett2_usb_get() pero no verifica el resultado. Devuelve el error si fallo en lugar de continuar con un valor no válido. • https://git.kernel.org/stable/c/9e15fae6c51a362418f8b3054f1322c54675df94 https://git.kernel.org/stable/c/51d5697e1c0380d482c3eab002bfc8d0be177e99 https://git.kernel.org/stable/c/be96acd3eaa790d10a5b33e65267f52d02f6ad88 https://git.kernel.org/stable/c/996fde492ad9b9563ee483b363af40d7696a8467 https://git.kernel.org/stable/c/145c5aa51486171025ab47f35cff34bff8d0cea3 https://git.kernel.org/stable/c/ca459dfa7d4ed9098fcf13e410963be6ae9b6bf3 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52691 – drm/amd/pm: fix a double-free in si_dpm_init
https://notcve.org/view.php?id=CVE-2023-52691
In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix a double-free in si_dpm_init When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/pm: corrige una double free en si_dpm_init Cuando fallo la asignación de adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries, se llama a amdgpu_free_extended_power_table para liberar algunos campos de adev. Sin embargo, cuando el flujo de control regresa a si_dpm_sw_init, va a la etiqueta dpm_failed y llama a si_dpm_fini, que llama a amdgpu_free_extended_power_table nuevamente y libera esos campos nuevamente. De este modo se activa un double free. • https://git.kernel.org/stable/c/841686df9f7d2942cfd94d024b8591fa3f74ef7c https://git.kernel.org/stable/c/afe9f5b871f86d58ecdc45b217b662227d7890d0 https://git.kernel.org/stable/c/06d95c99d5a4f5accdb79464076efe62e668c706 https://git.kernel.org/stable/c/aeed2b4e4a70c7568d4a5eecd6a109713c0dfbf4 https://git.kernel.org/stable/c/2bf47c89bbaca2bae16581ef1b28aaec0ade0334 https://git.kernel.org/stable/c/f957a1be647f7fc65926cbf572992ec2747a93f2 https://git.kernel.org/stable/c/fb1936cb587262cd539e84b34541abb06e42b2f9 https://git.kernel.org/stable/c/ca8e2e251c65e5a712f6025e27bd9b26d •
