Release Date: | 2024-06-21 |
In the Linux kernel, the following vulnerability has been resolved:\ndmaengine: idxd: Avoid unnecessary destruction of file_ida\nfile_ida is allocated during cdev open and is freed accordingly\nduring cdev release. This sequence is guaranteed by driver file\noperations. Therefore, there is no need to destroy an already empty\nfile_ida when the WQ cdev is removed.\nWorse, ida_free() in cdev release may happen after destruction of\nfile_ida per WQ cdev. This can lead to accessing an id in file_ida\nafter it has been destroyed, resulting in a kernel panic.\nRemove ida_destroy(&file_ida) to address these issues.
