{"id":"DEBIAN-CVE-2024-41083","details":"In the Linux kernel, the following vulnerability has been resolved:  netfs: Fix netfs_page_mkwrite() to check folio-\u003emapping is valid  Fix netfs_page_mkwrite() to check that folio-\u003emapping is valid once it has taken the folio lock (as filemap_page_mkwrite() does).  Without this, generic/247 occasionally oopses with something like the following:      BUG: kernel NULL pointer dereference, address: 0000000000000000     #PF: supervisor read access in kernel mode     #PF: error_code(0x0000) - not-present page      RIP: 0010:trace_event_raw_event_netfs_folio+0x61/0xc0     ...
