CVE-2011-1163 is a vulnerability of currently unknown severity. The osf_partition function in fs/partitions/osf.c in the Linux kernel before 2.6.38 does not properly handle an invalid number of partitions, which might allow local users to obtain potentially sensitive information from kernel heap memory via vectors related to partition-table parsing.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
