CVE-2018-14615

Se ha descubierto un problema en el kernel de Linux hasta la versión 4.17.10. Existe un desbordamiento de búfer en truncate_inline_inode() en fs/f2fs/inline.c cuando se desmonta una imagen f2fs porque un valor de longitud puede ser negativo.

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.
