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 •

In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv: Add a null pointer check to scom_debug_init_one() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Add a null pointer check, and release 'ent' to avoid memory leaks. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powerpc/powernv: agregue una verificación de puntero null a scom_debug_init_one() kasprintf() devuelve un puntero a la memoria asignada dinámicamente que puede ser NULL en caso de fallo. Agregue una verificación de puntero null y suelte 'ent' para evitar pérdidas de memoria. • https://git.kernel.org/stable/c/bfd2f0d49aef8abfe6bf58f12719f39912993cc6 https://git.kernel.org/stable/c/f84c1446daa552e9699da8d1f8375eac0f65edc7 https://git.kernel.org/stable/c/1eefa93faf69188540b08b024794fa90b1d82e8b https://git.kernel.org/stable/c/2a82c4439b903639e0a1f21990cd399fb0a49c19 https://git.kernel.org/stable/c/ed8d023cfa97b559db58c0e1afdd2eec7a83d8f2 https://git.kernel.org/stable/c/dd8422ff271c22058560832fc3006324ded895a9 https://git.kernel.org/stable/c/a9c05cbb6644a2103c75b6906e9dafb9981ebd13 https://git.kernel.org/stable/c/9a260f2dd827bbc82cc60eb4f4d8c2270 •

In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: Add missing mutex lock around get meter levels As scarlett2_meter_ctl_get() uses meter_level_map[], the data_mutex should be locked while accessing it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: scarlett2: agrega un bloqueo mutex faltante alrededor de los niveles de obtención de medidores. Como scarlett2_meter_ctl_get() usa meter_level_map[], el data_mutex debe estar bloqueado al acceder a él. • https://git.kernel.org/stable/c/3473185f31df29ac572be94fdb87ad8267108bec https://git.kernel.org/stable/c/74e3de7cdcc31ce75ab42350ae0946eff62a2da2 https://git.kernel.org/stable/c/993f7b42fa066b055e3a19b7f76ad8157c0927a0 •

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix the error handler of rfkill config When the core rfkill config throws error, it should free the allocated resources. Currently it is not freeing the core pdev create resources. Avoid this issue by calling the core pdev destroy in the error handler of core rfkill config. Found this issue in the code review and it is compile tested only. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: corrige el controlador de errores de la configuración de rfkill Cuando la configuración principal de rfkill arroja un error, debería liberar los recursos asignados.
