The vulnerability of the netfspagemkwrite function in the fs/netfs/bufferedwrite.c module of the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2024-41083

A flaw was found in netfspagemkwrite in the Linux kernel caused by a missing validation check for folio-mapping after acquiring the folio lock. This oversight could lead to a NULL pointer dereference, resulting in kernel crashes when handling file operations. The issue arose from interference by...
