CVE-2024-36006

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mlxsw: spectrum_acl_tcam: Fix incorrect list API usage<br /> <br /> Both the function that migrates all the chunks within a region and the<br /> function that migrates all the entries within a chunk call<br /> list_first_entry() on the respective lists without checking that the<br /> lists are not empty. This is incorrect usage of the API, which leads to<br /> the following warning [1].<br /> <br /> Fix by returning if the lists are empty as there is nothing to migrate<br /> in this case.<br /> <br /> [1]<br /> WARNING: CPU: 0 PID: 6437 at drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_tcam.c:1266 mlxsw_sp_acl_tcam_vchunk_migrate_all+0x1f1/0&gt;<br /> Modules linked in:<br /> CPU: 0 PID: 6437 Comm: kworker/0:37 Not tainted 6.9.0-rc3-custom-00883-g94a65f079ef6 #39<br /> Hardware name: Mellanox Technologies Ltd.
