Описание
The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL.
Отчет
This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not backport the upstream commit 4b580ee3 that introduced this issue. This has been addressed in Red Hat Enterprise Linux 5, 6, and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0429.html, https://rhn.redhat.com/errata/RHSA-2011-0542.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html.
