A denial-of-service vulnerability has been identified in the Linux kernel, stemming from an out-of-bounds overflow. This flaw occurs when the requested memory mapping region size exceeds the allocated region size. An attacker can exploit this by crafting a specially designed file, which, when processed by the kernel, could trigger an overflow. This leads to a system crash, impacting the availability of the affected system.
