The vulnerability, which currently\u00a0remains\u00a0unpatched, has been described as a successor to the previously disclosed Copy Fail flaw tracked as CVE-2026-31431.<\/span><span data-ccp-props=\"{\"134233117\":false,\"134233118\":false,\"335551550\":0,\"335551620\":0,\"335559738\":240,\"335559739\":240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Security researcher Hyunwoo Kim, also known online as @v4bel, publicly\u00a0disclosed\u00a0the issue after what he described as a breakdown in the coordinated disclosure and embargo process. The vulnerability was initially reported to Linux kernel maintainers on April 30, 2026, but no official fixes or CVE identifiers had been assigned at the time of disclosure.<\/span><span data-ccp-props=\"{\"134233117\":false,\"134233118\":false,\"335551550\":0,\"335551620\":0,\"335559738\":240,\"335559739\":240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">According to Kim, Dirty Frag is not a single bug but a vulnerability class capable of achieving root privileges across many Linux distributions by chaining together two separate flaws: the\u00a0xfrm-ESP Page-Cache Write vulnerability and the\u00a0RxRPC\u00a0Page-Cache Write vulnerability.<\/span><span data-ccp-props=\"{\"134233117\":false,\"134233118\":false,\"335551550\":0,\"335551620\":0,\"335559738\":240,\"335559739\":240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Kim explained in his technical write-up:<\/span><span data-ccp-props=\"{\"134233117\":false,\"134233118\":false,\"335551550\":0,\"335551620\":0,\"335559738\":240,\"335559739\":240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">\u201cDirty Frag is a vulnerability (class) that achieves root privileges on most Linux distributions by chaining the\u00a0xfrm-ESP Page-Cache Write vulnerability and the\u00a0RxRPC\u00a0Page-Cache Write vulnerability.\u201d<\/span><span

that Dirty Frag extends the same bug class associated with Dirty Pipe and Copy Fail (CVE-2026-31431).\u00a0Unlike race-condition-based attacks, Dirty Frag operates through a deterministic logic flaw, making exploitation more reliable.<\/span><span
