CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-42256 – cifs: Fix server re-repick on subrequest retry
https://notcve.org/view.php?id=CVE-2024-42256
In the Linux kernel, the following vulnerability has been resolved: cifs: Fix server re-repick on subrequest retry When a subrequest is marked for needing retry, netfs will call cifs_prepare_write() which will make cifs repick the server for the op before renegotiating credits; it then calls cifs_issue_write() which invokes smb2_async_writev() - which re-repicks the server. If a different server is then selected, this causes the increment of server->in_flight to happen against one record and the decrement to happen against another, leading to misaccounting. Fix this by just removing the repick code in smb2_async_writev(). ... En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: corrige la repetición del servidor en el reintento de subrequest Cuando se marca una subrequest para necesitar un reintento, netfs llamará a cifs_prepare_write(), lo que hará que cifs vuelva a seleccionar el servidor para la operación antes de renegociar los créditos; luego llama a cifs_issue_write(), que invoca a smb2_async_writev(), que vuelve a seleccionar el servidor. • https://git.kernel.org/stable/c/3ee1a1fc39819906f04d6c62c180e760cd3a689d https://git.kernel.org/stable/c/b1d0a566769b6fb3795b5289fc1daf9e0638d97a https://git.kernel.org/stable/c/de40579b903883274fe203865f29d66b168b7236 •
