CVE-2024-40937

MEDIUM

Linux Kernel 5.14-5.15.161, 5.16-6.1.94, 6.2-6.6.34, 6.7-6.9.5 - Use-After-Free in gve_rx_free_skb

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: gve: Clear napi->skb before dev_kfree_skb_any() gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it is freed with dev_kfree_skb_any(). This can result in a subsequent call to napi_get_frags returning a dangling pointer. Fix this by clearing napi->skb before the skb is freed.
