NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debuginfo package and not the kernel-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

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

mmc: via-sdmmc: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, it will lead two issues:

  1. The memory that allocated in mmc_alloc_host() is leaked.
  2. In the remove() path, mmc_remove_host() will be called to delete device, but it's not added yet, it will lead a kernel crash because of null-ptr-deref in device_del().

Fix this by checking the return value and goto error path which will call mmc_free_host().
