CVE-2010-3477
Published: 21 September 2010
The tcf_act_police_dump function in net/sched/act_police.c in the actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc4 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel memory via vectors involving a dump operation. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2942.
From the Ubuntu Security Team
Eric Dumazet discovered that many network functions could leak kernel stack contents. A local attacker could exploit this to read portions of kernel memory, leading to a loss of privacy.
