Linux Kernel TIPC NULL Pointer Dereference Vulnerability

Vulnerability

A NULL pointer dereference vulnerability has been identified in the Linux kernel's TIPC (Transparent Inter-Process Communication) module. This issue arises when a broadcast link is created after a node is inserted into the hashtable, creating a window where a broadcast packet can be received and attempt to dereference a link that is still NULL, leading to a crash.

Impact

Exploitation of this vulnerability causes a kernel panic due to a NULL pointer dereference, crashing the system.
