A flaw was found in the HDLC_PPP module of the Linux kernel in versions
before 5.9-rc7. Memory corruption and a read overflow is caused by improper
input validation in the ppp_cp_parse_cr function which can cause the system
to crash or cause a denial of service. The highest threat from this
vulnerability is to data confidentiality and integrity as well as system
availability.
