When the CONFIG_PAGE_OWNER option is enabled, the kernel's memory management (mm/vmalloc) component can experience Read-Copy-Update (RCU) stalls during virtual memory allocation cleanup. This occurs because freeing Kernel Address Sanitizer (KASAN) shadow pages triggers expensive stack unwinding operations that acquire RCU read locks. Processing a large number of pages without yielding the CPU can cause tasks to hold the CPU for extended periods, leading to RCU stalls and potential Out-Of-Memory (OOM) conditions, effectively resulting in a Denial of Service."], "name": "CVE-2026-43292", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Out of support scope", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2026-05-08T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-43292\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-43292\nhttps://lore.kernel.org/linux-cve-announce/2026050853-CVE-2026-43292-a97d@gregkh/T"], "threat_severity": "Moderate"}
