CVE-2020-35499
Last modified
CVE-2020-35499 is a medium-severity vulnerability rated 6.7/10 on the CVSS scale. A NULL pointer dereference flaw in Linux kernel versions prior to 5.11 may be seen if sco_sock_getsockopt function in net/bluetooth/sco.c do not have a sanity check for a socket connection, when using BT_SNDMTU/BT_RCVMTU for SCO sockets. This could allow a local attacker with a special user privilege to crash the system (DOS) or leak kernel internal information.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
