CVE-2022-49345

The CVE-2022-49345 issue affects the Linux kernel’s net: xfrm subsystem, where __init-annotated xfrm4_protocol_init() is exported via EXPORT_SYMBOL, causing use-after-free risk when __init and EXPORT_SYMBOL co-exist. The root cause is the .init text is freed after init, so modules could access fr...
