{"id":"DEBIAN-CVE-2024-26595","details":"In the Linux kernel, the following vulnerability has been resolved:  mlxsw: spectrum_acl_tcam: Fix NULL pointer dereference in error path  When calling mlxsw_sp_acl_tcam_region_destroy() from an error path after failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region-\u003egroup-\u003etcam' [1].  Fix by retrieving the 'tcam' pointer using mlxsw_sp_acl_to_tcam().
