Descriptions
A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
Se encontró un fallo de uso de memoria previamente liberada en el sistema de archivos NILFS del kernel de Linux en la forma en que el usuario desencadena la función security_inode_alloc para que falle con la siguiente llamada a la función nilfs_mdt_destroy. Un usuario local podría usar este fallo para bloquear el sistema o escalar potencialmente sus privilegios en el sistema.
Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the memory address space accounting implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
