* kernel: fat: fix uninitialized field in nostale filehandles (CVE-2024-26973)

* kernel: wifi: rtw89: fix null pointer access when abort scan (CVE-2024-35946)

* kernel: net/usb: kalmia: Don't pass act_len in usb_bulk_msg error path (CVE-2023-52703)

* kernel: Input: synaptics-rmi4 - fix use after free in rmi_unregister_function() (CVE-2023-52840)

* kernel: usbnet: sanity check for maxpacket (CVE-2021-47495)

* kernel: drm/dp_mst: Fix resetting msg rx state after topology removal (CVE-2024-57876)

* kernel: vsock: Keep the binding until socket destruction (CVE-2025-21756)

* kernel: net: ppp: Add bound checking for skb data on ppp_sync_txmung (CVE-2025-37749)

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-2025:8248.
