CVE-2011-1090 (CCN-65937)

Assigned:2011-03-05
Published:2011-03-05
Updated:2023-02-13
Summary: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.
