Which kernel versions does the udev exploit work? Upon googling this, I found articles claiming that it works on Android 2.1 and maybe 2.2, but there is no information about the kernel versions.

    We can't help you find the kernel, as it would be considered a shopping recommendation -- this may be helpful with that however. Jan 13 '12 at 17:03
  • I am just trying to do some research, for which I need the kernel version. I don't want to buy a device. I am not going to shop for anything. Jan 13 '12 at 17:07
  • Whether you pay money is irrelevant -- searching for something to acquire (the kernel) is shopping by SE's standards. We can help you figure out when the exploit was patched / the versions where it is unpatched, but actually finding somewhere to get the kernel is off-topic. See the FAQ. Jan 13 '12 at 17:09

    Fine, can you tell me the kernel version. Jan 13 '12 at 17:11

I'm actually not sure that the kernel version matters for this exploit. It was a bug that was patched in the platform_system_core repository, which I think comprises libraries and system files that live on in the /system directory (the README says as much). The patch was committed on July 19, 2010 (in the Froyo branch, anyway).

I'd wager that any kernel with a build date later than that also has the updated system files, so the system wouldn't be vulnerable. uname -a would tell you the build date of a given device's kernel, but beyond that I don't know that you could really line it up with a specific kernel version, especially on devices from different manufacturers/carriers/etc.

  • The patch should be helpful. Now I'll just unpatch that patch on the kernel that test the exploit. That should work right? Jan 13 '12 at 19:02
  • @EknathIyer: Sure, if you reversed the diff the code would be exploitable again, I would assume. Jan 13 '12 at 19:11
