Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： media: ipu6：初始化后不要释放辅助设备的 pdata 函数会将 isys/psys 的 指针存储在 中，并初始化辅助设备（auxiliary device）。在此之后，错误回退（unwinding）流程必须释放辅助设备的引用，并由 负责释放总线设备（bus device）和 。 由于 isys 和 psys 的初始化路径在 MMU 初始化失败时已经调用了 ，而 在 失败时会调用 ，因此这两个路径都会执行总线设备的 release 回调函数。如果调用者中额外添加

Vulnerability Title
media: ipu6: Do not free aux device pdata after init
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: media: ipu6: Do not free aux device pdata after init ipu6_bus_initialize_device() stores the isys/psys pdata pointer in struct ipu6_bus_device and initializes the auxiliary device. After that point, error unwinding must drop the auxiliary device reference and let ipu6_bus_release() free both the bus device and adev->pdata. The isys and psys init paths already call put_device() when MMU initialization fails, and ipu6_bus_add_device() calls auxiliary_device_uninit() on auxiliary_device_add() failure. Both paths therefore run the bus release callback. The extra kfree(pdata) in the callers can release the same object a second time. Remove the manual pdata frees after the auxiliary device has been initialized. This issue was found by a static analysis checker and confirmed by manual source review.
