Description OSIDB Bzimport 2026-08-15 06:05:17 UTC
In the Linux kernel, the following vulnerability has been resolved:

uprobes/x86: Use proper mm_struct in __in_uprobe_trampoline

In the unregister path we use __in_uprobe_trampoline check with
current->mm for the VMA lookup, which is wrong, because we are
in the tracer context, not the traced process.

Add mm_struct pointer argument to __in_uprobe_trampoline and
changing related callers to pass proper mm_struct pointer.
