Description

uprobes: fix kernel info leak via "[uprobes]" vma

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
