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: libceph: fix potential use-after-free in have_mon_and_osd_map() (CVE-2025-68285)

  • kernel: libceph: make decode_pool() more resilient against corrupted osdmaps (CVE-2025-71116)

  • kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done() (CVE-2026-22984)

  • kernel: libceph: replace overzealous BUG_ON in osdmap_apply_incremental() (CVE-2026-22990)

  • kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state (CVE-2026-23136)

  • 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: af_unix: Drop all SCM attributes for SOCKMAP (CVE-2026-53005)

  • 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)

  • kernel: nvme-tcp: fix host memory disclosure on R2T for a read command (CVE-2026-89481)

Bug Fix(es) and Enhancement(s):

  • Bypass DMA APIs for coherent allocations for pre-mapped memory [rhel-10.2.z] (JIRA:Rocky Linux-252331)
