kernel: use-after-free in net/atm/ioctl.c

A use-after-free flaw was found in the Linux kernel's net/atm/ioctl.c ATM networking technology driver: dovccioctl in net/atm/ioctl.c is vulnerable to use-after-free due to a race condition in vccrecvmsg. This issue can allow an attacker to possibly gain unauthorized access, escalate privileges, ...
