CVE-2015-7799: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 4.2.2
