CVE-2019-15666: Debian Linux

Medium severity, CVSS 4.4. EPSS: 1.7% chance of exploitation in the next 30 days.

An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.

Affected products

• Debian Debian Linux: version 8.0 only
• Linux Linux Kernel: before 5.0.19 (fixed in 5.0.19)
• Opensuse Leap: version 15.0 only; version 15.1 only
