Description
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.
