CVE-2026-43124

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pstore: ram_core: fix incorrect success return when vmap() fails<br /> <br /> In persistent_ram_vmap(), vmap() may return NULL on failure.<br /> <br /> If offset is non-zero, adding offset_in_page(start) causes the function<br /> to return a non-NULL pointer even though the mapping failed.<br /> persistent_ram_buffer_map() therefore incorrectly returns success.<br /> <br /> Subsequent access to prz-&gt;buffer may dereference an invalid address<br /> and cause crashes.<br /> <br /> Add proper NULL checking for vmap() failures.
