In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: use the Rx queue napi pointer to find the napi vector The queue management ndos pick the napi vector for an Rx queue with: nv = fbn-napiidx % fbn-numnapi; The issue is this is only correct in the cases where there are...

UBUNTU-CVE-2026-98460

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisock: reject out-of-range OCF values The raw HCI socket security filter has 128 OCF bits per supported OGF, but masks the 10-bit OCF with 127 before looking up the command. An unprivileged socket can therefore submi...

UBUNTU-CVE-2026-98718

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Do cache maintenance on the source VM before clearing SEV state Explicitly flush caches after intra-host migration before clearing "SEV active" on the source VM, as doing cache maintenance afterwards creates a tiny wind...

In the Linux kernel, the following vulnerability has been resolved: iio: adc: adsigmadelta: fix use-after-free on unbind adsdbufferpostenable allocates sigmadelta-samplesbuf with devmkrealloc at runtime, so its devres entry sits after all probe-time entries of the driver. devm resources are...

UBUNTU-CVE-2026-98557

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: fix header length used by gvecansendtso for UDP GSO gvecansendtso computes how many buffers each segment of a GSO packet would span, and for this it needs the length of the headers that the device replicates in front of...

CVE-2026-98556

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: reject TSO packets with an out of range MSS gvepreptso notes that the device requires the MSS to be len and gsosegs, never gsosize. Such a packet reaches gvetxfilltsoctxdesc, which puts gsosize into the mss field of the...
