Kernel Zero-Day 'Dirty Frag' e Shatter Cloud Trust joalo ka ha Google Acro Agents e fetola E-commerce

Sebopeho sa theknoloji se lula se fetoha, empa liphetoho tse ling ke tsa tectonic. Bekeng ena, re tobane le liketsahalo tse peli tse joalo: letsatsi la bohlokoa la Linux kernel, le bitsoang 'Dirty Frag,' le nyenyefatsang litiiso tsa ts'ireletso ea lisebelisoa tsa sejoale-joale tsa maru, le "Universal Cart Acro" ea Google, e ts'episang ho nchafatsa maemo a khoebo ea inthaneteng ka AI ea khale. Ka bobeli li hloka tlhahlobo e potlakileng, e matla ea tekheniki ho tsoa mohahong o mong le o mong oa moenjiniere le ho boloka lefatše la rona la dijithale.

Ka la 7 Mots'eanong 2026, phatlalatso e hlabosang e ile ea romela lits'oants'o ho sechaba sa ts'ireletso sa Linux: bofokoli bo bongata ba kernel, CVE-2026-43284 le CVE-2026-43500, hammoho tse tsejoang e le 'Dirty Frag.' Sena ha se feela keketseho ea litokelo tsa lehae (LPE); ke tsela e ikemiselitseng ho tloha ho mosebelisi ea se nang tokelo ho ea ho metso, ho feta mabokose a lehlabathe - lijana le li-microVM - tse etsang motheo oa ts'ireletso ea tlhaho ea maru.

Sebaka sa Tšokelo: Ho nyenyefatsa li-Primitives tsa ho itšehla thajana

Mehaho ea morao-rao ea maru e itšetlehile haholo ka ho itšehla thajana. Docker, Kubernetes, esita le mechini e bobebe e bobebe joalo ka Firecracker le Kata Containers e ts'episa meeli e matla lipakeng tsa meroalo ea mosebetsi. Dirty Frag e senya thetso ena. Taba ea mantlha e ka hare ho tsamaiso ea memori ea Linux kernel, haholo-holo hore na e sebetsana joang le likabelo tsa memori tse arohaneng le li-deallocations.

Leha lintlha tse ikhethileng tsa tšebeliso e mpe li ntse li hlaha, tlhahlobo ea rona e fana ka maikutlo a hore 'Dirty Frag' e eketsa ts'ebello e tsoetseng pele ea ts'ebeliso ea morao-rao (UAF) ka har'a kernel ea SLUB allocator, eo mohlomong e bakiloeng ke maemo a morabe a kenyelletsang ts'ebetso ea mmap kapa tšebelisano e rarahaneng le mefuta e meng ea li-socket tsa marang-rang (mohlala, AF_PAC kapa AF_PAC). "Frag" moniker e supa bokhoni ba mohlaseli ba ho qhekella karohano ea kernel qubu, ho theha meralo e ka lebelloang ea mohopolo e lumellang kabo e tšepahalang ea data e laoloang ke mosebelisi ho sekotjana sa ntho e lokolotsoeng ea kernel.

Mona ke letoto le utloahalang, la ts'ebeliso ea maemo a holimo:

  1. Ho qala UAF: Ts'ebetso e sa tsitsang e qala letoto la likabo tsa memori le lipehelo, mohlomong tse kenyelletsang ts'ebetso ea shmem kapa io_uring, e etselitsoeng ho theha mokhoa o ikhethileng oa ho arohana ka har'a qubu ea kernel. Boemo ba morabe bo lumella ntho ea kernel hore e lokolloe ha pointer ea khale e ntse e le teng.
  2. Heap Spray & Re-Allocation: Sehlaseli se ntan'o "fafatsa" qubu ea kernel ka data e laoloang ke basebelisi, hangata ka msg_msg kapa pipe_buffer lintho, ka sepheo sa ho abela botjha data ya bona sebakeng sa mohopolo sa kernel e lokollotsweng.
  3. Ho Balla/Ngola ho sa Feleng: Ka data e laoloang e se e le nthong ea kernel, mohlaseli a ka etsa meroalo e kotsi ho fumana kernel e baloang/e ngola ea khale. Sena se ka kenyelletsa ho senya sebopeho sa seq_operations kapa tafole ea file_operations.

  1. Beha Pele ho Lits'oants'o tsa Dirty Frag: Hang-hang tsebahatsa litsamaiso tsohle tse thehiloeng ho Linux, haholo tse tsamaisang lijana kapa li-microVM. Sebetsa le mofani oa hau oa maru kapa morekisi oa phepelo ho sebelisa li-patches tsa kernel (CVE-2026-43284, CVE-2026-43500) hang ha li fumaneha.
