https://notcve.org/view.php?id=CVE-2022-48699
In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in update_sched_domain_debugfs Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup()) leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory. Fix this up by using the newly created debugfs_lookup_and_remove() call instead which properly handles the dentry reference counting logic. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sched/debug: corrige la fuga de dentry en update_sched_domain_debugfs Kuyo informa que el patrón de uso de debugfs_remove(debugfs_lookup()) pierde un dentry y con una prueba de estrés de conexión en caliente, la máquina eventualmente se queda sin memoria. Solucione este problema utilizando la llamada debugfs_lookup_and_remove() recién creada, que maneja adecuadamente la lógica de conteo de referencias de dentry. • https://git.kernel.org/stable/c/26e9a1ded8923510e5529fbb28390b22228700c2 https://git.kernel.org/stable/c/0c32a93963e03c03e561d5a066eedad211880ba3 https://git.kernel.org/stable/c/c2e406596571659451f4b95e37ddfd5a8ef1d0dc •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix memory leak when using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up by properly calling dput().

In the Linux kernel, the following vulnerability has been resolved: peci: cpu: Fix use-after-free in adev_release() When auxiliary_device_add() returns an error, auxiliary_device_uninit() is called, which causes refcount for device to be decremented and .release callback will be triggered.

CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-27057 – ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend
https://notcve.org/view.php?id=CVE-2024-27057
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ASoC: SOF: ipc4-pcm: workaround para firmware bloqueado en suspensión del sistema Cuando el sistema se suspende mientras el audio está activo, se invoca sof_ipc4_pcm_hw_free() para restablecer las canalizaciones desde durante la suspensión el DSP está apagado, las transmisiones se reiniciarán después de reanudarse. Si el firmware falla mientras se ejecuta el audio (o cuando reiniciamos la transmisión antes de suspenderla), entonces sof_ipc4_set_multi_pipeline_state() fallará con un error de IPC y se interrumpirá el cambio de estado. Esto provocará una desalineación entre el estado del kernel y del firmware en el siguiente arranque del DSP, lo que provocará errores devueltos por el firmware para los mensajes IPC, lo que eventualmente provocará un error en la reanudación del audio. Al cerrar la transmisión, los errores se ignoran, por lo que el estado del kernel se corregirá en el siguiente inicio del DSP, es decir, en el segundo inicio después del pánico del DSP. • https://git.kernel.org/stable/c/3cac6eebea9b4bc5f041e157e45c76e212ad6759 https://git.kernel.org/stable/c/d153e8b154f9746ac969c85a4e6474760453647c https://git.kernel.org/stable/c/c40aad7c81e5fba34b70123ed7ce3397fa62a4d2 •
