UBUNTU-CVE-2024-49940

In the Linux kernel, the following vulnerability has been resolved: l2tp: prevent possible tunnel refcount underflow When a session is created, it sets a backpointer to its tunnel. When the session refcount drops to 0, l2tpsessionfree drops the tunnel refcount if session-tunnel is non-NULL...

CVE-2024-49988 ksmbd: add refcnt to ksmbd_conn struct

In the Linux kernel, the following vulnerability has been resolved: ksmbd: add refcnt to ksmbdconn struct When sending an oplock break request, opinfo-conn is used, But freed -conn can be used on multichannel. This patch add a reference count to the ksmbdconn struct so that it can be freed when i...

CVE-2024-49988

The CVE-2024-49988 issue concerns the ksmbd kernel SMB server: during an oplock break, opinfo->conn could be used after ksmbd_conn is freed in multichannel scenarios. The fix adds a reference count to ksmbd_conn to ensure it is not freed while still in use. This is a Linux kernel-level vulnera...
