CVE-2022-50623
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
