The vulnerability of the `udpDestroySock()` function in the `net/ipv4/udp.c` module of the Linux operating system’s kernel-based IPv4 protocol implementation allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the udpDestroySock function in the net/ipv4/udp.c module of the Linux kernel’s IPv4 protocol implementation is related to synchronization errors when using shared resources. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, an...
