  3. CVE-2024-40924
In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm->bound_list. Then it tries to rewrite the PTEs via a stale CPU mapping. This causes panic. [vsyrjala: Add TODO comment] (cherry picked from commit 51064d471c53dcc8eddd2333c3f1c1d9131ba36c)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/i915/dpt: hacer que el objeto DPT no se pueda reducir. En algunos escenarios, el objeto DPT se reduce pero el framebuffer real no y, por lo tanto, sigue ahí en vm->bound_list del DPT. Luego intenta reescribir las PTE mediante una asignación de CPU obsoleta. Esto provoca pánico. [vsyrjala: Agregar comentario TODO] (seleccionado del commit 51064d471c53dcc8eddd2333c3f1c1d9131ba36c)
