Name of the Vulnerable Software and Affected Versions

Description
The issue is related to a use-after-free condition in the do vcc ioctl function in the net/atm/ioctl.c module of the Linux kernel, caused by a vcc recvmsg race condition. This could potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information.
Recommendations
For versions prior to 6.6.8, update to version 6.6.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the
do vcc ioctl() function in the net/atm/ioctl.c module until a patch is available.Fix
