Descriptions

In the Linux kernel, the following vulnerability has been resolved:

nvme-tcp: fix UAF when detecting digest errors

We should also bail from the io_work loop when we set rd_enabled to true,
so we don't attempt to read data from the socket when the TCP stream is
already out-of-sync or corrupted.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvme-tcp: corrige UAF al detectar errores de resumen. También debemos salir del bucle io_work cuando configuramos rd_enabled en verdadero, para no intentar leer datos del socket cuando el flujo TCP ya no está sincronizado o está dañado.

A use-after-free vulnerability was found in the Linux kernel in drivers/nvme/host/tcp.c in nvme_tcp_io_work. This issue can occur when a local user continues to read data after the connection finishes. This flaw allows a malicious user to cause a use-after-free problem.
