CVE-2015-5706
Published: 3 August 2015
Use-after-free vulnerability in the path_openat function in fs/namei.c in the Linux kernel 3.x and 4.x before 4.0.4 allows local users to cause a denial of service or possibly have unspecified other impact via O_TMPFILE filesystem operations that leverage a duplicate cleanup operation.
From the Ubuntu Security Team
A double free flaw was discovered in the Linux kernel's path lookup. A local user could cause a denial of service (Oops).
