CVE-2018-14616

Se ha descubierto un problema en el kernel de Linux hasta la versión 4.17.10. Hay una desreferencia de puntero NULL en fscrypt_do_page_crypto() en fs/crypto/crypto.c cuando se opera en un archivo en una imagen f2fs corrupta.

It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. Various other issues were also addressed.
