kernel: Linux kernel: Memory leak in wilc1000 Wi-Fi driver causes Denial of Service
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix potential memory leak in wilc_mac_xmit()
The wilc_mac_xmit() returns NETDEV_TX_OK without freeing skb, add
dev_kfree_skb() to fix it. Compile tested only.
A flaw was found in the Linux kernel's wilc1000 Wi-Fi driver. A local attacker with low privileges could exploit a memory leak in the wilc_mac_xmit() function, which fails to free a socket buffer (skb) under certain conditions. This resource exhaustion vulnerability can lead to a Denial of Service (DoS) on the affected system.
