CVE-2026-98057 ring-buffer: Add checking nr_subbufs to persistent ring buffer validation

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Add checking nrsubbufs to persistent ring buffer validation Sashiko reported that the code was using meta-nrsubbufs without making sure that it matched the nrpages + 1 on data that was assuming the two were the same...

CVE-2026-98057

The Linux kernel contains a vulnerability in the ring-buffer component. The issue arises because the code utilized meta->nr_subbufs without verifying that it correctly matched nr_pages + 1, despite the system assuming these two values were identical. To resolve this, a check was added to the p...

CVE-2026-97997 virtio_ring: fix stale descriptor flags after a failed packed add

In the Linux kernel, the following vulnerability has been resolved: virtioring: fix stale descriptor flags after a failed packed add In a packed ring the AVAIL and USED bits sit in the descriptor itself, so writing them makes that descriptor available. Those bit combinations flip meaning on every...

CVE-2026-97997

The Linux kernel contains a vulnerability in the virtio_ring component where a failed packed add can leave stale AVAIL and USED bits in the descriptors. When vring_map_one_sg() fails mid-operation, unmap_release restores flags but leaves descriptors marked as available. This causes the device to ...

CVE-2026-97953

A vulnerability exists in the Linux kernel 's stmmac driver related to the TX descriptor availability check for TSO traffic . The stmmac_tso_xmit() function incorrectly estimates the required free TX descriptors by assuming the payload is split into TSO_MAX_BUFF_SIZE chunks. This logic underestim...
