Description

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Properly handle NULL pointer in dat_cond_set_storage_key() Some callers pass NULL as oldkey. Calling page_cond_set_storage_key() will cause that NULL pointer to get dereferenced. Fix by checking for NULL and assigning the pointer to a dummy local variable to avoid crashes.

CVE-2026-98723

In the Linux kernel, the following vulnerability has been resolved: nvmet: copy the hostid into the ctrl before creating PR pc_refs Commit 6202783184bf ("nvmet: Improve nvmet_alloc_ctrl() interface and implementation") added a second uuid_copy() of args->hostid near the end of nvmet_alloc_ctrl(), and commit 7b658153f1b8 ("nvmet: Remove duplicate uuid_copy") removed the original copy that sat before nvmet_ctrl_init_pr() instead of the new one. Since then nvmet_ctrl_init_pr() snapshots ctrl->hostid into the per-controller per-namespace reservation refs while the uuid_copy() from the connect data runs later, after the controller is published. The ctrl is allocated with kzalloc(), so every pc_ref created on this path stores the nil UUID. pc_ref->hostid has a single consumer: nvmet_pr_set_ctrl_to_abort() matches it against the preempted registrant's hostid to kill and drain the victim's in-flight I/O for Preempt and Abort. The match can never hit with the nil UUID, so whenever a namespace with reservations enabled exists before a host connects, which includes every reconnect, Preempt and Abort silently degrades into a plain Preempt: the preempting host sees success while the victim's in-flight I/O is still in the air. Copy the hostid where the rest of the connect data is consumed, before the controller is published and before nvmet_ctrl_init_pr() takes its snapshot.

CVE-2026-98619

A race condition in the Linux kernel’s ethtool ETHTOOL_TEST ioctl allows an offline self test to tear down and reconfigure a network interface without holding the required rtnl_lock. This can lead to device instability or crashes on ops‑locked drivers. The issue is limited to the ioctl path and affects specific drivers such as fbnic and bnxt.

CVE-2026-98622

This CVE involves a benign warning in the Linux kernel's traffic control conntrack action that can be triggered by an unprivileged user to cause a kernel panic when panic_on_warn is enabled. The issue arises when flow_offload_alloc() fails during a conntrack flush race. The patch removes the warning, preventing the panic.

CVE-2026-98623

CVE-2026-98623 is a medium‑severity vulnerability in the Linux kernel’s Nouveau driver that allows an out‑of‑bounds read via the debugfs interface. The flaw occurs when an invalid pstate ID is supplied to nvkm_clk_ustate_update, causing a kernel memory read. It can potentially expose sensitive kernel data to privileged users.
