Описание
In the Linux kernel, the following vulnerability has been resolved:
net: qcom/emac: fix UAF in emac_remove
adpt is netdev private data and it cannot be
used after free_netdev() call. Using adpt 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 Qualcomm EMAC driver, where the emac_remove function can lead to a use-after-free issue when the driver tries to access data after the network device has been freed, causing instability and a crash in the network subsystem.
Отчет
This vulnerability is rated as a moderate severity because the use-after-free can disrupt the network operations, leading to potential service interruptions, but it does not directly expose sensitive data; it may result in system instability.
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.
