Descriptions
A flaw was found in the Linux kernel’s io_uring implementation. This flaw allows an attacker with a local account to corrupt system memory, crash the system or escalate privileges.
Se ha encontrado un fallo en la implementación io_uring del kernel de Linux. Este fallo permite a un atacante con una cuenta local corromper la memoria del sistema, bloquear el sistema o escalar privilegios
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the handling of credentials in io_uring. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.
