CVE-2012-2375: Linux Kernel

Medium severity, CVSS 4.6. EPSS: 1% chance of exploitation in the next 30 days.

The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131.

Affected products

• Linux Linux Kernel: up to and including 3.3.1; version 3.3 only
