CVE-2011-1090
Publication date 9 May 2011
Last updated 24 July 2024
Ubuntu priority
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.
From the Ubuntu Security Team
Neil Horman discovered that NFSv4 did not correctly handle certain orders of operation with ACL data. A remote attacker with access to an NFSv4 mount could exploit this to crash the system, leading to a denial of service.
