CVE-2016-2069

Published: 26 January 2016

Race condition in arch/x86/mm/tlb.c in the Linux kernel before 4.4.1 allows local users to gain privileges by triggering access to a paging structure by a different CPU.

From the Ubuntu security team

Andy Lutomirski discovered a race condition in the Linux kernel's translation lookaside buffer (TLB) handling of flush events. A local attacker could use this to cause a denial of service or possibly leak sensitive information.

Priority

Medium

CVSS 3 base score: 7.4
