kernel: Linux kernel: libceph stack out-of-bounds write via crafted OSDMap

A flaw was found in libceph in the Linux kernel. A remote attacker, acting as a malicious monitor, could send a specially crafted OSDMap Object Storage Device Map with an overly long pgtemp or pgupmap entry. This could lead to a stack out-of-bounds write, resulting in a kernel bug and potentially...
