FKIE_CVE-2024-49954
Vulnerability from fkie_nvd - Published: 2024-10-21 18:15 - Updated: 2026-06-17 08:00
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
static_call: Replace pointless WARN_ON() in static_call_module_notify()
static_call_module_notify() triggers a WARN_ON(), when memory allocation
fails in __static_call_add_module().
That's not really justified, because the failure case must be correctly
handled by the well known call chain and the error code is passed
through to the initiating userspace application.
A memory allocation fail is not a fatal problem, but the WARN_ON() takes
the machine out when panic_on_warn is set.
Replace it with a pr_warn().
