CVE-2022-49726 clocksource: hyper-v: unexport __init-annotated hv_init_clocksource()

In the Linux kernel, the following vulnerability has been resolved: clocksource: hyper-v: unexport init-annotated hvinitclocksource EXPORTSYMBOL and init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated init. The...

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...
