CVE-2022-49886

The CVE-2022-49886 issue affects the Linux kernel related to x86/tdx memory handling. The vulnerability stems from how private memory (TDX private memory, including kernel stacks/text) may trigger a virtualization exception (#VE) and the difficulty of handling such exceptions. The root cause desc...

CVE-2022-49802 ftrace: Fix null pointer dereference in ftrace_add_mod()

In the Linux kernel, the following vulnerability has been resolved: ftrace: Fix null pointer dereference in ftraceaddmod The @ftracemod is allocated by kzalloc, so both the members prev,next of @ftracemode-list are NULL, it's not a valid state to call listdel. If kstrdup for @ftracemod-func|modul...

CVE-2022-49802

CVE-2022-49802 affects the Linux kernel ftrace: a NULL pointer dereference can occur in ftrace_add_mod() when ftrace_mod was not initialized as a list head. The issue arises because kzalloc() can leave list pointers NULL and code may call list_del() on an uninitialized entry, triggering an Oops a...
