Descriptions
In the Linux kernel, the following vulnerability has been resolved:
of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: of: módulo: agregar control de desbordamiento del búfer of_modalias() En of_modalias(), si el búfer es demasiado pequeño incluso para la primera llamada a snprintf(), el parámetro len se vuelve negativo y el parámetro str (si no es NULL inicialmente) apuntará más allá del final del búfer. Agregue la verificación de desbordamiento del búfer después de la primera llamada a snprintf() y corrija dicha verificación después de la llamada strlen() (teniendo en cuenta el carácter NUL de terminación).
A buffer overflow flaw was found in of_modalias() in the Linux kernel, occurring after the first snprintf() call. This issue could result in loss of availability of the system.
