The vulnerability of the reqskqueueunlink function in the net/ipv4/inetconnectionsock.c module of the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

kernel: tcp: make sure init the accept_queue's spinlocks once

In the Linux kernel, the following vulnerability has been resolved: tcp: make sure init the acceptqueue's spinlocks once When I run syz's reproduction C program locally, it causes the following issue: pvqspinlock: lock 0xffff9d181cd5c660 has corrupted value 0x0! WARNING: CPU: 19 PID: 21160 at...

The vulnerability of the implementation of the Upper Level Protocol (ULP) in the Linux operating system allows a hacker to enhance their privileges, execute arbitrary code, or cause a service failure.

The vulnerability in the implementation of the Upper Level Protocol ULP in the Linux kernel’s inetconnectionsock.c file is related to improper handling of sockets that are in the LISTEN state in certain protocols. This leads to the reallocation of previously freed memory. Exploiting this...
