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: crypto: af_alg - zero initialize memory allocated via sock_kmalloc (CVE-2025-71113)

  • kernel: Linux kernel: Denial of Service due to memory leak in tpm2_load_cmd (CVE-2025-71147)

  • kernel: flex_proportions: make fprop_new_period() hardirq safe (CVE-2026-23168)

  • kernel: cxl/port: Fix use after free of parent_port in cxl_detach_ep() (CVE-2026-31530)

  • kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete (CVE-2026-46116)

  • kernel: fanotify: fix false positive on permission events (CVE-2026-46150)

  • kernel: drm: Set old handle to NULL before prime swap in change_handle (CVE-2026-46215)

  • kernel: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl() (CVE-2026-52976)

  • kernel: drm/xe/dma-buf: fix UAF with retry loop (CVE-2026-52950)

  • kernel: ice: fix double-free of tx_buf skb (CVE-2026-53009)

  • kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp (CVE-2026-53071)

  • kernel: can: bcm: thrtimer use-after-free during RX operation teardown ()

Bug Fix(es) and Enhancement(s):

  • nfsd_file slab cache objects remaining on kmem_cache_shutdown during nfsd teardown while running bz1477872 testcase (JIRA:Rocky Linux-173103)

  • tools/lib/perf/Makefile: libperf includes appended after CFLAGS causes parallel build race, breaking kernel builds [rhel-10.2.z] (JIRA:Rocky Linux-183975)

  • [Rocky Linux10-debug]: BUG: KASAN: slab-use-after-free in __pv_queued_spin_lock_slowpath [rhel-10.2.z] (JIRA:Rocky Linux-186311)

  • ice: driver update 2026-06, part 1 [rhel-10.2.z] (JIRA:Rocky Linux-191324)
