CVE-2024-49975

In the Linux kernel, the following vulnerability has been resolved: uprobes: fix kernel info leak via "[uprobes]" vma xol_add_vma() maps the uninitialized page allocated by __create_xol_area() into userspace. On some architectures (x86) this memory is readable even without VM_READ, VM_EXEC results in the same pgprot_t as VM_EXEC|VM_READ, although this doesn't really matter, debugger can read this memory anyway.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: uprobes: se corrige la fuga de información del kernel a través de "[uprobes]" vma xol_add_vma() asigna la página no inicializada asignada por __create_xol_area() al espacio de usuario. En algunas arquitecturas (x86), esta memoria se puede leer incluso sin VM_READ, VM_EXEC da como resultado el mismo pgprot_t que VM_EXEC|VM_READ, aunque esto realmente no importa, el depurador puede leer esta memoria de todos modos.
