NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

usb-storage: alauda: Check whether the media is initialized

The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba().

  • Add a member "media_initialized" to struct alauda_info.
  • Change a condition in alauda_check_media() to ensure the first initialization.
  • Add an error check for the return value of alauda_init_media().
