CVE-2012-6549: Infoleak

Q: What is the severity of CVE-2012-6549?

CVE-2012-6549 has been classified as a medium severity vulnerability due to its potential to expose sensitive information from kernel heap memory to local users.

Q: How can I fix CVE-2012-6549?

To fix CVE-2012-6549, you should upgrade your Linux kernel to version 3.6 or later, which contains the necessary patches.

Q: What versions of the Linux kernel are affected by CVE-2012-6549?

CVE-2012-6549 affects Linux kernel versions before 3.6, including all 3.5.x versions and earlier.

Q: Is CVE-2012-6549 exploitable remotely?

No, CVE-2012-6549 is not exploitable remotely; it requires local access for exploitation.

Q: Which Linux distributions are likely affected by CVE-2012-6549?

Linux distributions such as Debian, Ubuntu, and others that use affected kernels prior to version 3.6 are likely vulnerable to CVE-2012-6549.

Updated

Last updated 24 July 2024

Other sources

The isofsexportencodefh function in fs/isofs/export.c in the Linux kernel before 3.6 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted application.
