Descriptions

An issue was discovered in the Linux kernel before 6.3.4. ksmbd has an out-of-bounds read in smb2_find_context_vals when create_context's name_len is larger than the tag length.

Se descubrió un problema en el kernel de Linux antes de 6.3.4. KSMBD tiene una lectura fuera de los límites en smb2_find_context_vals cuando el name_len de create_context es mayor que la longitud de la etiqueta.

Zi Fan Tan discovered that the binder IPC implementation 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. It was discovered that a race condition existed in the f2fs file system in the Linux kernel, leading to a null pointer dereference vulnerability. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service.
