CVE-2026-98617

A flaw was found in the Linux kernel's Meta Host Network Interface fbnic driver. The driver incorrectly associates receive queues with network processing vectors and fails to verify whether the datapath is active before allocating queue memory. A privileged local user could trigger this flaw duri...

CVE-2026-98616

A flaw was found in the Linux kernel's fbnic driver. This flaw allows a local user to trigger a kernel crash, resulting in a Denial of Service DoS. During power management suspend or failed resume operations, the driver frees interrupt vectors without clearing the active vector counter. When the...
