CVE-2025-22104

The CVE-2025-22104 issue concerns the ibmvnic driver in the Linux kernel. The root cause was printing hex dumps by casting the buffer to an 8-byte long and using string formatters, which could trigger a read buffer overflow if the buffer size isn’t a multiple of 8. The fix introduces a new ibmvni...
