CVE-2022-49236

CVE-2022-49236 concerns a Linux kernel use-after-free in BPF/BTF handling: a race between module init and module reuse could allow BTF IDs to be published before a module is fully live. The fix, as described in the related documentation, is to set a BTF_MODULE_F_LIVE flag at MODULE_STATE_LIVE so ...
