Nj\u00eb vulnerabilitet \u00ebsht\u00eb zbuluar n\u00eb kernelin Linux CVE-2026-43499<\/a>, i njohur si GhostLock. Problemi prek kodin rtmutex dhe mekanizmin futex me trash\u00ebgimin\u00eb e prioritetit, dhe shfryt\u00ebzimi i tij mund t\u00eb lejoj\u00eb nj\u00eb p\u00ebrdorues lokal pa privilegje t\u00eb ngriste t\u00eb drejtat n\u00eb root. Sipas AlmaLinux<\/a>, vulnerabiliteti gjithashtu mund t\u00eb p\u00ebrdoret nga nj\u00eb konteiner p\u00ebr t\u00eb dal\u00eb n\u00eb host n\u00ebse sistemi funksionon me nj\u00eb kernel t\u00eb pa p\u00ebrdit\u00ebsuar.<\/p>\n

Thelbi i gabimit lidhet me funksionin remove_waiter() n\u00eb kernel\/locking\/rtmutex.c.

Si rezultat, gjendja pi_blocked_on mund t\u00eb mos pastronte si duhet, duke l\u00ebn\u00eb nj\u00eb tregues pezull dhe duke krijuar kushte p\u00ebr use-after-free.<\/p>\n

Korrektimi n\u00eb upstream konsiston n\u00eb at\u00eb q\u00eb remove_waiter() duhet t\u00eb p\u00ebrdor\u00eb waiter::task, jo current, n\u00eb t\u00eb gjitha operacionet e lidhura. Kjo \u00ebsht\u00eb e theksuar gjithashtu n\u00eb GitHub Advisory Database<\/a>, ku jan\u00eb p\u00ebrmendur pasojat e gabimit: heqje jokorrekte nga rbtree pa bllokim t\u00eb nevojsh\u00ebm, gjendje e pastruar pi_blocked_on dhe funksionimi i rt_mutex_adjust_prio_chain() jo me at\u00eb detyr\u00eb.<\/p>\n
