Security Fix(es): * kernel: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation (CVE-2026-43133) * kernel: ipv6: prevent possible UaF in addrconf_permanent_addr() (CVE-2026-43339) * kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests (CVE-2026-43493) * kernel: tcp: call sk_data_ready() after listener migration (CVE-2026-46015) * kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show() (CVE-2026-46149) * kernel: inet: RAW sockets using IPPROTO_RAW MUST drop incoming ICMP (CVE-2026-46266) * kernel: flow_dissector: do not dissect PPPoE PFC frames (CVE-2026-46306) * kernel: Revert "net/smc: Introduce TCP ULP support" (CVE-2026-46330) * kernel: netfilter: conntrack: remove sprintf usage (CVE-2026-53002) * kernel: net: guard timestamp cmsgs to real error queue skbs (CVE-2026-53223) * kernel: ipv6: mcast: Fix use-after-free when processing MLD queries (CVE-2026-53275) * kernel: ipv4: account for fraggap on the paged allocation path (CVE-2026-53366) * kernel: net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer (CVE-2026-64034) * kernel: rhashtable: clear stale iter->p on table restart (CVE-2026-64563) * kernel: smb: client: fix double-free in SMB2_close() replay (CVE-2026-64597) * kernel: nvmet-rdma: handle inline data with a nonzero offset (CVE-2026-72129) * kernel: net: bridge: stop fast-leave after deleting a port group (CVE-2026-74480) Bug Fix(es) and Enhancement(s): * KSM to deduplicate only zero pages [rhel-9.8.z] (JIRA:RHEL-249161) 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: wifi: mt76: mt7925: fix crash in reset link replay During reset recovery, mt7925_vif_connect_iter() replays firmware state for links tracked in mvif->valid_links. After MLO link changes or MCU timeout recovery, the driver bitmap can temporarily contain a link whose mac80211 bss_conf has already gone away. This can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching the crash where x1, the second argument, is NULL: pc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib] lr : mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common] x2 : ffffff80a77f6018 x1 : 0000000000000000 x0 : ffffff8099402080 Call trace: mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib] mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common] mt7925_mac_reset_work+0x264/0x2f8 [mt7925_common] Skip missing bss_conf entries before replaying the link. Non-MLO AP/STA reset replay is unchanged because the helper still returns &vif->bss_conf for the legacy link.
