Synopsis

Important: kernel security, bug fix, and enhancement update

Type/Severity

Security Advisory: Important

Topic

An update for kernel is now available for Red Hat Enterprise Linux 9.6 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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

Security Fix(es):

  • kernel: Squashfs: sanity check symbolic link size (CVE-2024-46744)

  • kernel: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item (CVE-2025-68211)

  • kernel: Bluetooth: SCO: fix race conditions in sco_sock_connect() (CVE-2026-43023)

  • kernel: netfilter: nft_set_pipapo_avx2: don't return non-matching entry on expiry (CVE-2026-43114)

  • kernel: Bluetooth: hci_event: fix potential UAF in SSP passkey handlers (CVE-2026-46056)

  • kernel: RDMA/mana: Validate rx_hash_key_len (CVE-2026-46145)

  • kernel: ipv6: fix possible UAF in icmpv6_rcv() (CVE-2026-53006)

  • kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table() (CVE-2026-64002)

  • kernel: crypto: qat - validate RSA CRT component lengths (CVE-2026-64304)

  • kernel: net: bridge: stop fast-leave after deleting a port group (CVE-2026-74480)

  • kernel: vhost: reset the vring metadata cache on vring reconfiguration (CVE-2026-74580)

Bug Fix(es) and Enhancement(s):

  • [RHEL 9] Bonding reports unknown speed/duplex for tg3 interface [rhel-9.6.z] (JIRA:RHEL-182767)

  • [RHEL9] tlbflush - Windows Driver Verifier catches FLTMGR/Ntfs crashes during KVM 42-VM soak test on AMD EPYC Turin [rhel-9.6.z] (JIRA:RHEL-214435)

  • vhost: reset the vring metadata cache on vring reconfiguration [rhel-9.6.z] (JIRA:RHEL-224548)

  • [RHEL9] BUG: KASAN: global-out-of-bounds in scsi_sysfs_add_host+0x179/0x1b0 [rhel-9.6.z] (JIRA:RHEL-234440)

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture.

Because of this proactive approach, a patch may be associated with a CVE assignment at a future date. Retroactive CVE assignments are always documented in the corresponding errata and on Red Hat's CVE pages. We strongly advise against delaying updates, as doing so may leave your system exposed when protections are already available.
