A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device resulting in a denial of service. The highest threat from this vulnerability is to system availability.
