CVE-2022-49726

CVE-2022-49726 concerns the Linux kernel clocksource for Hyper-V. The issue arises from exporting an __init-annotated hv_init_clocksource() symbol, while the __init code may be freed after initialization, making the symbol potentially invalid for modules. The vulnerability can lead to a kernel pa...
