CVE-2021-47310

EPSS Низкий

Описание

In the Linux kernel, the following vulnerability has been resolved: net: ti: fix UAF in tlan_remove_one priv is netdev private data and it cannot be used after free_netdev() call. Using priv after free_netdev() can cause UAF bug. Fix it by moving free_netdev() at the end of the function.

A vulnerability was found in the Linux kernel's TI TLAN driver, where the tlan_remove_one function can lead to a use-after-free issue when the driver attempts to access private data after the network device has already been freed, potentially causing system instability or crash.

Отчет

This vulnerability is rated as a moderate because the use-after-free can disrupt network functionality, resulting in service interruptions, but it does not directly compromise sensitive information.

Меры по смягчению последствий

Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
