CVE-2026-89750

A flaw was found in the Linux kernel's tracing/userevents component. This vulnerability arises when a child process, created via fork, exits and frees memory that the parent process still references. This creates a Use-After-Free UAF condition, where the parent process attempts to access freed...

CVE-2026-89750

CVE-2026-89750 is a Use-After-Free vulnerability in the Linux kernel's tracing/user_events subsystem. During fork, dup_task_struct() copies the user_event_mm pointer from the parent into the child without acquiring a reference. If user_event_mm_alloc() subsequently fails, the stale pointer is lef...
