Description

The ping_recvmsg function in net/ipv4/ping.c in the Linux kernel before 3.12.4 does not properly interact with read system calls on ping sockets, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging unspecified privileges to execute a crafted application.

Affected products

Linux kernel: through 3.12.3; 3.0-rc1, 3.0-rc2, 3.0-rc3, 3.0-rc4, 3.0-rc5, 3.0-rc6 (+277)
