Doc Text:
A vulnerability was found in the Linux kernel in the gdm_lte_rx() function in drivers/staging/gdm724x/gdm_lte.c where an issue arises from a use-after-free condition, as the netif_rx_ni() function frees the skb, making subsequent access to skb->len unsafe, lead to potential memory corruption or crashes.

Description OSIDB Bzimport 2024-07-16 13:24:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

staging: gdm724x: fix use after free in gdm_lte_rx()

The netif_rx_ni() function frees the skb so we can't dereference it to
save the skb->len.
