| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the explicit allocation of
cpumask variable on the stack in the Linux kernel, which can cause a potential stack overflow for kernels configured with CONFIG CPUMASK OFFSTACK=y. Instead, the kernel code should use *cpumask var API(s) to allocate cpumask var in a config-neutral way. The vulnerability in the iucv cpu down prep() function in the net/iucv/iucv.c module is associated with writing memory beyond the allocated buffer, which can allow an attacker to impact the confidentiality, integrity, and availability of protected information.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
