RHEL 10 : kernel (RHSA-2025:22854)

medium Nessus Plugin ID 277828

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:22854 advisory.

 The kernel packages contain the Linux kernel, the core of any Linux operating system.

 Security Fix(es):

 * kernel: cifs: Fix oops due to uninitialised variable (CVE-2025-38737)

 * kernel: can: j1939: implement NETDEV_UNREGISTER notification handler (CVE-2025-39925)

 * kernel: Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync (CVE-2025-39982)

 * kernel: Bluetooth: MGMT: Fix possible UAFs (CVE-2025-39981)

 * kernel: net/mlx5: fs, fix UAF in flow counter release (CVE-2025-39979)

 * kernel: Bluetooth: hci_event: Fix UAF in hci_conn_tx_dequeue (CVE-2025-39983)

 * kernel: io_uring/waitid: always prune wait queue entry in io_waitid_wait() (CVE-2025-40047)

 * kernel: iommu/vt-d: Disallow dirty tracking if incoherent page walk (CVE-2025-40058)

 * kernel: ice: ice_adapter: release xa entry on adapter allocation failure (CVE-2025-40185)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2025:22854.
