Summary
Important: kernel security, bug fix, and enhancement update
Details

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

Security Fix(es):

  • kernel: fbcon: Set fb_display[i]->mode to NULL when the mode is released (CVE-2025-40323)

  • kernel: smb: smbdirect: introduce smbdirect_socket.recv_io.credits.available (CVE-2026-31539)

  • kernel: drm/amdgpu/vcn3: Prevent OOB reads when parsing dec msg (CVE-2026-46230)

  • kernel: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB (CVE-2026-46204)

  • kernel: drm/amdgpu/vcn4: Prevent OOB reads when parsing dec msg (CVE-2026-46199)

  • kernel: drm/amdgpu/userq: fix access to stale wptr mapping (CVE-2026-46311)

  • kernel: netfilter: nf_queue: hold bridge skb->dev while queued (CVE-2026-52912)

  • kernel: accel/ivpu: Add buffer overflow check in MS get_info_ioctl (CVE-2026-53203)

  • kernel: drm/xe/eustall: Fix drm_dev_put called before stream disable in close (CVE-2026-53290)

  • kernel: drm/virtio: use uninterruptible resv lock for plane updates (CVE-2026-64098)

  • kernel: Linux kernel: PPPoE memory corruption via stale pointer (CVE-2026-68121)

  • kernel: drm/amdgpu/vce: fix integer overflow in image size (CVE-2026-68108)

  • kernel: drm/amdkfd: fix 32-bit overflow in CWSR total size calculation (CVE-2026-68257)

  • kernel: drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists (CVE-2026-68267)

  • kernel: drm/xe: Hold a dma-buf reference for imported BOs (CVE-2026-68266)

  • kernel: drm/amdgpu: Fix context pstate override handling (CVE-2026-68273)

  • kernel: Linux kernel IPVS: Denial of Service due to stale memory references (CVE-2026-80714)

Bug Fix(es) and Enhancement(s):

  • MADVISE i/o size in Rocky Linux 9 additionally limited by read_ahead_kb - Was addressed in Rocky Linux8 via Rocky Linux-22476 [rhel-9.8.z] (JIRA:Rocky Linux-260938)
