VendorlinuxProductlinux kernelDiscoveredJul 25, 2025UpdatedNov 19, 2025

In the Linux kernel, the following vulnerability has been resolved: idpf: return 0 size for RSS key if not supported Returning -EOPNOTSUPP from function returning u32 is leading to cast and invalid size value as a result. -EOPNOTSUPP as a size probably will lead to allocation fail. Command: ethtool -x eth0 It is visible on all devices that don't have RSS caps set.
