Answer in brief
CVE-2022-50623 records a High severity (CVSS 7.8) vulnerability in fpga: prevent integer overflow in dfl_feature_ioctl_set_irq(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: fpga: prevent integer overflow in dfl_feature_ioctl_set_irq() The "hdr.count * sizeof(s32)" multiplication can overflow on 32 bit systems leading to memory corruption. Use array_size() to fix that.
