| Subject: CVE-2024-49975: uprobes: fix kernel info leak via "[uprobes]" vma |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-49975 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
