Descriptions

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF in smb2_is_valid_lease_break() Skip sessions that are being teared down (status == SES_EXITING) to
avoid UAF.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: smb: cliente: corrige UAF potencial en smb2_is_valid_lease_break() Omita las sesiones que se están eliminando (estado == SES_EXITING) para evitar UAF.

A use-after-free flaw was found in the Linux kernel in smb smb2_is_valid_lease_break() when exiting a session. This flaw allows a local attacker to crash the system.

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF in smb2_is_valid_lease_break() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF.

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Attila Sz�sz discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code.
