02 May 2016 — Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service (disk corruption) by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling.

https://notcve.org/view.php?id=CVE-2015-4176
02 May 2016 — fs/namespace.c in the Linux kernel before 4.0.2 does not properly support mount connectivity, which allows local users to read arbitrary files by leveraging user-namespace root access for deletion of a file or directory. fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.2 no soporta correctamente conectividad de montaje, lo que permite a usuarios locales leer archivos arbitrarios aprovechando acceso root al espacio de nombres de usuario para eliminar un archivo o directorio. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e0c9c0afd2fc958ffa34b697972721d81df8a56f • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2015-2672
https://notcve.org/view.php?id=CVE-2015-2672
02 May 2016 — The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstr_replacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service (panic) by triggering a fault, as demonstrated by an unaligned memory operand or a non-canonical address memory operand.

02 May 2016 — The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.
