Double Free Vulnerability in Linux Kernel's DVB-Core Component

CVE-2022-50499

What is CVE-2022-50499?

A vulnerability in the Linux kernel's DVB-core component can lead to a double free error, occurring during the process of registering a media device. If the initialization of dvb->entity fails, the function incorrectly attempts to free the entity again during error handling, which may cause a use after free condition. This flaw potentially compromises system integrity and stability by allowing attackers to manipulate memory allocation processes. Proper handling of memory freeing is vital to ensure the security and reliability of the Linux kernel.
