Summary
Important: kernel-rt security and bug fix 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: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390)
  • kernel: netfilter: nf_tables: fix chain binding transaction logic in the abort path of NFT_MSG_NEWRULE (CVE-2023-3610)
  • kernel: net/sched: cls_fw component can be exploited as result of failure in tcf_change_indev function (CVE-2023-3776)
  • kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove() (CVE-2023-4004)
  • kernel: netfilter: nf_tables_newrule when adding a rule with NFTA_RULE_CHAIN_ID leads to use-after-free (CVE-2023-4147)
  • kernel: nf_tables: use-after-free in nft_chain_lookup_byid() (CVE-2023-31248)
  • kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval() (CVE-2023-35001)
  • kernel: save/restore speculative MSRs during S3 suspend/resume (CVE-2023-1637)
  • hw: amd: Cross-Process Information Leak (CVE-2023-20593)
  • kernel: bypass of shadow stack protection due to a logic error (CVE-2023-21102)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

  • kernel-rt: update RT source tree to the latest AlmaLinux-9.2.z3 Batch (BZ#2228482)
