CVE-2015-8966
Published: 8 December 2016
arch/arm/kernel/sys_oabi-compat.c in the Linux kernel before 4.4 allows local users to gain privileges via a crafted (1) F_OFD_GETLK, (2) F_OFD_SETLK, or (3) F_OFD_SETLKW command in an fcntl64 system call.
From the Ubuntu Security Team
It was discovered that the fcntl64() system call in the Linux kernel did not properly set memory limits when returning on 32-bit ARM processors. A local attacker could use this to gain administrative privileges.

|---|---|
| ratliff | the fix commit is dated Dec. 2015 |
| jdstrand | android kernels (flo, goldfish, grouper, maguro, mako and manta) are not supported on the Ubuntu Touch 14.10 and earlier preview kernels linux-lts-saucy no longer receives official support linux-lts-quantal no longer receives official support |
| sbeattie | this was probably introduced with the Open File Descriptor Locks patches in the 3.15 kernel, likely 5d50ffd7. |
