Red Hat has issued a security advisory for a kernel update addressing two vulnerabilities in the Linux kernel. The first vulnerability (CVE-2025-68811) involves the svcrdma component and fixes the use of rc_pageoff for memcpy byte offset. The second vulnerability (CVE-2026-23209) addresses error recovery in the macvlan component's macvlan_common_newlink() function. These issues affect Red Hat Enterprise Linux 10.0 Extended Update Support and related variants. The update is rated as having a moderate security impact. Systems must be rebooted after applying the update for the fixes to take effect.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: RDMA/rxe: Fix the qp flush warnings in req (CVE-2024-53229) * kernel: Kernel: Double free vulnerability in exFAT filesystem can lead to denial of service (CVE-2025-38206) * kernel: sctp: avoid NULL dereference when chunk data buffer is missing (CVE-2025-40240) * kernel: ipv6: BUG() in pskb_expand_head() as part of calipso_skbuff_setattr() (CVE-2025-71085) * kernel: svcrdma: use rc_pageoff for memcpy byte offset (CVE-2025-68811) 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.

In the Linux kernel, the following vulnerability has been resolved: svcrdma: use rc_pageoff for memcpy byte offset svc_rdma_copy_inline_range added rc_curpage (page index) to the page base instead of the byte offset rc_pageoff. Use rc_pageoff so copies land within the current page. Found by ZeroPath (https://zeropath.com)
