Stack Overflow in Linux Kernel's QoS Configuration Buffer by Hisilicon

CVE-2022-50407

What is CVE-2022-50407?

A vulnerability in the Linux kernel's Hisilicon QM module allows for a potential stack overflow due to insufficient checks on the length of the 'val buffer' during QoS configuration. The current buffer length is set to only 32 bytes, while the maximum expected length is 256 bytes. This oversight can lead to memory corruption and security implications, highlighting the importance of proactive mitigation strategies.
