Name of the Vulnerable Software and Affected Versions Linux kernel versions through 5.16.8

Description The issue is related to the mishandling of dev->buf release in the drivers/usb/gadget/legacy/inode.c component of the Linux kernel. This can lead to a use-after-free condition, potentially allowing an attacker to cause a denial of service or execute arbitrary code, resulting in local escalation of privilege without needing additional execution privileges. User interaction is not required for exploitation.

Recommendations For Linux kernel versions through 5.16.8, update to a version later than 5.16.8 to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable inode.c component until a patch is available.
