CVE-2022-49289

  2. Vulnerabilities (CVE)
  3. CVE-2022-49289
In the Linux kernel, the following vulnerability has been resolved: uaccess: fix integer overflow on access_ok() Three architectures check the end of a user access against the address limit without taking a possible overflow into account. Passing a negative length or another overflow in here returns success when it should not. Use the most common correct implementation here, which optimizes for a constant 'size' argument, and turns the common case into a single comparison.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: uaccess: fix entire entiret overflow on access_ok() Tres arquitecturas comprueban el final de un acceso de usuario contra el límite de direcciones sin tener en cuenta un posible desbordamiento. Pasar una longitud negativa u otro desbordamiento aquí devuelve éxito cuando no debería. Utilice la implementación correcta más común aquí, que optimiza para un argumento de "tamaño" constante y convierte el caso común en una única comparación.
