Summary
Important: kernel-rt security update
Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • kernel: HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove() (CVE-2025-21928)
  • kernel: memstick: rtsx_usb_ms: Fix slab-use-after-free in rtsx_usb_ms_drv_remove (CVE-2025-22020)
  • kernel: net_sched: hfsc: Fix a UAF vulnerability in class with netem as child qdisc (CVE-2025-37890)
  • kernel: net/tipc: fix slab-use-after-free Read in tipc_aead_encrypt_done (CVE-2025-38052)
  • kernel: crypto: algif_hash - fix double free in hash_accept (CVE-2025-38079)
  • kernel: ext4: avoid resizing to a partial cluster size (CVE-2022-50020)
