CVE-2015-7799 is a vulnerability of currently unknown severity. The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call.. EPSS estimates a 0.65% chance of exploitation in the next 30 days.
