https://notcve.org/view.php?id=CVE-2023-52694
In the Linux kernel, the following vulnerability has been resolved: drm/bridge: tpd12s015: Drop buggy __exit annotation for remove function With tpd12s015_remove() marked with __exit this function is discarded when the driver is compiled as a built-in. The result is that when the driver unbinds there is no cleanup done which results in resource leakage or worse. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/bridge: tpd12s015: Eliminar anotación __exit con errores para eliminar función Con tpd12s015_remove() marcado con __exit, esta función se descarta cuando el controlador se compila como integrado. El resultado es que cuando el controlador se desvincula no se realiza ninguna limpieza, lo que resulta en una fuga de recursos o algo peor. • https://git.kernel.org/stable/c/cff5e6f7e83f6271ed75972e9a2920e2c7f62d6c https://git.kernel.org/stable/c/53926e2a39629702f7f809d614b3ca89c2478205 https://git.kernel.org/stable/c/08ccff6ece35f08e8107e975903c370d849089e5 https://git.kernel.org/stable/c/81f1bd85960b7a089a91e679ff7cd2524390bbf1 https://git.kernel.org/stable/c/a8657406e12aa10412134622c58977ac657f16d2 https://git.kernel.org/stable/c/e00ec5901954d85b39b5f10f94e60ab9af463eb1 https://git.kernel.org/stable/c/ce3e112e7ae854249d8755906acc5f27e1542114 https://lists.debian.org/debian-lts-announce/2024/06/ •
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. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE. • https://git.kernel.org/stable/c/9661e92c10a9775243c1ecb73373528ed8725a10 https://git.kernel.org/stable/c/556f02699d33c1f40b1b31bd25828ce08fa165d8 https://git.kernel.org/stable/c/1e3a2b9b4039bb4d136dca59fb31e06465e056f3 https://git.kernel.org/stable/c/c4e1a0ef0b4782854c9b77a333ca912b392bed2f https://git.kernel.org/stable/c/3a370502a5681986f9828e43be75ce26c6ab24af https://git.kernel.org/stable/c/2124c5bc22948fc4d09a23db4a8acdccc7d21e95 https://git.kernel.org/stable/c/39af144b6d01d9b40f52e5d773e653957e6c379c https://git.kernel.org/stable/c/72884ce4e10417b1233b614bf134da852 •

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.

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 •
