The vulnerability of the __dst_negative_advice() function in the Linux operating system’s IPv4 kernel protocol allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.
The vulnerability of the dstnegativeadvice function in the include/net/sock.h module of the Linux operating system’s IPv4 kernel implementation is related to the reutilization of previously freed memory due to competitive access to resources race condition. Exploiting this vulnerability could all...
