CVE-2025-39959
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp: Fix incorrect retrival of acp_chip_info Use dev_get_drvdata(dev->parent) instead of dev_get_platdata(dev) to correctly obtain acp_chip_info members in the acp I2S driver. Previously, some members were not updated properly due to incorrect data access, which could potentially lead to null pointer dereferences. This issue was missed in the earlier commit ("ASoC: amd: acp: Fix NULL pointer deref in acp_i2s_set_tdm_slot"), which only addressed set_tdm_slot(). This change ensures that all relevant functions correctly retrieve acp_chip_info, preventing further null pointer dereference issues.

Anteriormente, algunos miembros no se actualizaban correctamente debido a un acceso incorrecto a los datos, lo que podría conducir potencialmente a desreferencias de puntero nulo.\n\nEste problema se pasó por alto en el commit anterior ('ASoC: amd: acp: Fix NULL pointer deref in acp_i2s_set_tdm_slot'), que solo abordaba set_tdm_slot(). Este cambio asegura que todas las funciones relevantes recuperen correctamente acp_chip_info, previniendo problemas adicionales de desreferencia de puntero nulo."
