Descriptions
A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their privileges on the system.
Se encontró una falla de desreferencia de puntero nulo en la API del kernel de Linux para la funcionalidad de dispersión del algoritmo criptográfico. Este problema ocurre cuando un usuario construye un paquete malicioso con una configuración de socket específica, lo que podría permitir que un usuario local bloquee el sistema o aumente sus privilegios en el sistema.
It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Lonial Con discovered that the netfilter subsystem in the Linux kernel contained a memory leak when handling certain element flush operations. A local attacker could use this to expose sensitive information (kernel memory). Various other issues were also addressed.
