GHSA-73PJ-JQMG-PMR5

Vulnerability from github – Published: 2024-02-28 09:30 – Updated: 2024-12-06 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

i40e: Fix use-after-free in i40e_client_subtask()

Currently the call to i40e_client_del_instance frees the object pf->cinst, however pf->cinst->lan_info is being accessed after the free. Fix this by adding the missing return.

Addresses-Coverity: ("Read from pointer after free")

Severity ?

7.8 (High)
