CVE-2021-46954

CVE-2021-46954 affects the Linux kernel net/sched IPv4 path. When act_mirred attempts to fragment IPv4 packets that were previously reassembled by act_ct, sch_frag used a temporary dst_entry, which was later treated as an rtable pointer in the fragment/MTU flow. This caused a stack out-of-bounds ...
