CVE-2024-53175

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ipc: fix memleak if msg_init_ns failed in create_ipc_ns

Percpu memory allocation may failed during create_ipc_ns however this fail is not handled properly since ipc sysctls and mq sysctls is not released properly. Fix this by release these two resource when failure.

Here is the kmemleak stack when percpu failed:
