Descriptions

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

Se ha encontrado un fallo en la forma en que el miembro "flags" de la estructura del nuevo búfer de la tubería carecía de la inicialización apropiada en las funciones copy_page_to_iter_pipe y push_pipe en el kernel de Linux y, por tanto, podía contener valores obsoletos. Un usuario local no privilegiado podía usar este fallo para escribir en páginas de la caché de páginas respaldadas por archivos de sólo lectura y así escalar sus privilegios en el sistema

Linux versions 4.20 and above have an issue where ktls writes into spliced readonly pages.

Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system. This vulnerability has the moniker of "Dirty Pipe."
