CVE-2026-98841

The Linux kernel contains a vulnerability in the virt: vmgenid component where notification handlers are registered before driver_data is assigned. This improper ordering causes a kernel NULL pointer dereference and a system panic if an interrupt or ACPI notification occurs during the probe path....

CVE-2026-98821

The Linux kernel contains a vulnerability where IOPOLL calls bio_poll() on uio_meta instead of a bio structure when user integrity metadata is present. This occurs because IOCB_HAS_METADATA leaves iocb->private as uio_meta, but iocb_bio_iopoll() expects a bio, and since commit 2729a60bbfb9, me...

CVE-2026-98821 block: reject polled dio with user integrity metadata

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCBHASMETADATA leaves iocb-private as a uiometa, while iocbbioiopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdevdirectIO, which never publishes the bio...

CVE-2026-98812

A vulnerability exists in the Linux kernel 's net/mctp component where the mctp_add_dev() function incorrectly links a new mctp_dev into dev->mctp_ptr before the mdev->dev pointer is assigned. This race condition allows a reader to pick up the device in a window where it still points to NUL...

In the Linux kernel, the following vulnerability has been resolved: net: restrict SORESERVEMEM to TCP sockets and cap max value Commit 2bb2f5fb21b0 "net: add new socket option SORESERVEMEM" and commit d00c8ee31729 "net: fix possible NULL deref in sockreservememory" only checked skhasaccountsk,...

CVE-2026-98801

The Linux kernel contained a vulnerability where the SO_RESERVE_MEM socket option was improperly handled for UDP sockets . Because the kernel only checked for account ownership rather than protocol type, concurrent UDP packet reception and memory reservation calls could cause race conditions , le...

CVE-2026-98798 net: bcmgenet: fix NULL dereference in set_coalesce before first open

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix NULL dereference in setcoalesce before first open The Rx ring priv and index are only set in bcmgenetinitrxring, which runs at open. Setting the Rx coalescing parameters on an interface that was never opened,...

CVE-2026-98798

The Linux kernel contains a NULL dereference vulnerability in the bcmgenet driver. The issue occurs because the Rx ring priv and index are only initialized during the open operation. If a user attempts to set Rx coalescing parameters—for example, using ethtool -C eth0 rx-usecs 50—on an interface ...
