  • kernel: dm-integrity: don't increment hash_offset twice (CVE-2026-72099)

Bug Fix(es) and Enhancement(s):

  • [Rocky Linux 8.10] "kernel BUG at lib/list_debug.c:28!": list_add corruption in register_trace_event Rocky Linux 8.10 (JIRA:Rocky Linux-214136)

  • request_key_auth use-after-free on every request-key upcall since 4.18.0-553.165.1 (regression from CVE-2026-63823 backport) (JIRA:Rocky Linux-270349)
