Description
Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field.
A use-after-free flaw was observed in blkdev_get(), in fs/block_dev.c after a call to __blkdev_get() fails, and its refcount gets freed/released. This problem may cause a denial of service problem with a special user privilege, and may even lead to a confidentiality issue.
