A vulnerability has been found in Linux Kernel up to 5.10.162/5.15.85/6.0.15/6.1.1. The impacted element is the function btf_dump_name_dups of the file tools/lib/bpf/btf_dump.c of the component libbpf. The manipulation leads to use after free. Upgrading to version 5.10.163, 5.15.86, 6.0.16, 6.1.2 and 6.2 is sufficient to resolve this issue. The identifier of the patch is c61650b869e0b6fb0c0a28ed42d928eea969afc8/fbe08093fb2334549859829ef81d42570812597d/8c64a8e76eb85d422af5ec60ccbf26e3ead8c333/a733bf10198eb5bb927890940de8ab457491ed3b/93c660ca40b5d2f7c1b1626e955a8e9fa30e0749. You should upgrade the affected component.
