Vulnerability from gsd
Modified
2024-02-20 06:02
Details
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_flow_offload: release dst in case direct xmit path is used
Direct xmit does not use it since it calls dev_queue_xmit() to send
packets, hence it calls dst_release().
kmemleak reports:
unreferenced object 0xffff88814f440900 (size 184):
comm "softirq", pid 0, jiffies 4294951896
