What to do
AI-suggested
A fix for this vulnerability is available in the Linux kernel. Users and administrators should apply the official kernel updates that address this issue. Since this is a kernel-level vulnerability, updating to a patched kernel version is the recommended mitigation.
Description
CVE-2024-49975 is a medium-severity vulnerability in the Linux kernel involving an information leak via the "[uprobes]" virtual memory area (VMA). The flaw occurs because xol_add_vma() maps an uninitialized page allocated by __create_xol_area() into userspace. On some architectures like x86, this memory can be read by debuggers even without VM_READ permissions, due to how VM_EXEC permissions are handled. This issue has been resolved in the Linux kernel.
