The flaw resides in the kernel's IPsec\\n          ESP-in-TCP handling: when an ESP-encapsulated TCP segment containing a\\n          shared fragment (SKBFL_SHARED_FRAG) is received and decrypted, the AES-GCM keystream\\n          is applied to page cache pages of the target file without enforcing\\n          write permissions. This allows an unprivileged attacker to overwrite\\n          arbitrary bytes of a read-only file backed by the page cache. Upstream fix is ported\\n          independently by different vendors, so there's release version from which each kernel is\\n          not vulnerable anymore.\", \"disclosure_date\": \"2026-05-14\", \"fullname\": \"exploit/linux/local/cve_2026_46300_fragnesia\", \"is_install_path\": true, \"mod_time\": \"2026-07-28 10:23:14 +0000\", \"name\": \"Fragnesia LPE (CVE-2026-46300)\", \"needs_cleanup\": true, \"notes\": {\"Reliability\": [\"repeatable-session\"], \"SideEffects\": [\"artifacts-on-disk\", \"ioc-in-logs\"], \"Stability\": [\"crash-service-down\"]}, \"path\": \"/modules/exploits/linux/local/cve_2026_46300_fragnesia.rb\", \"platform\": \"Linux,Unix\", \"post_auth\": false, \"rank\": 500, \"ref_name\": \"linux/local/cve_2026_46300_fragnesia\", \"references\": [\"CVE-2026-46300\", \"URL-https://github.com/v12-security/pocs/tree/main/fragnesia\"], \"rport\": null, \"session_types\": [\"shell\", \"meterpreter\"], \"targets\": [\"Automatic\"], \"type\": \"exploit\"}", "creation_timestamp": "2026-09-08T06:49:07.606629Z"}
