CVE-2022-50579

CVE-2022-50579 affects the Linux kernel on arm64 with ftrace when modules use PLTs and mcount. The issue arises from a kata of the ftrace PLT handling after commit a6253579, where ftrace_make_nop() assumes the callsite uses the kernel trampoline PLT while module PLTs may be out-of-range. As modul...

SUSE CVE-2022-49721

In the Linux kernel, the following vulnerability has been resolved: arm64: ftrace: consistently handle PLTs. Sometimes it is necessary to use a PLT entry to call an ftrace trampoline. This is handled by ftracemakecall and ftracemakenop, with each having almost identical logic, but this is not...

CVE-2022-49721

CVE-2022-49721 affects the Linux kernel (arm64) ftrace. The root cause is inconsistent handling of PLT entries when calling ftrace trampolines: ftrace_modify_call() can produce out-of-range branches, causing warnings and no code change, or replace the old branch with a BRK, risking a kernel panic...
