Exploiting the DRAM rowhammer bug to gain kernel privileges
http://googleprojectzero.blogspot.ru/2015/03/exploiting-dram-rowhammer-bug-to-gain.html
“Rowhammer” is a problem with some recent DRAM devices in which repeatedly accessing a row of memory can cause bit flips in adjacent rows. We tested a selection of laptops and found that a subset of them exhibited the problem. We built two working privilege escalation exploits that use this effect. One exploit uses rowhammer-induced bit flips to gain kernel privileges on x86-64 Linux when run as an unprivileged userland process. When run on a machine vulnerable to the rowhammer problem, the process was able to induce bit flips in page table entries (PTEs). It was able to use this to gain write access to its own page table, and hence gain read-write access to all of physical memory.
нихуясебе
@plhk два дня тока прошло хуле ты
@lexszero ясно
@plhk не у всех работает, да, хуево сделано
@plhk чо за комп/память?
у меня на t430 за 10 минут не воспроизвелось, забил хуй.
