CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2023-52664 – net: atlantic: eliminate double free in error handling logic
https://notcve.org/view.php?id=CVE-2023-52664
In the Linux kernel, the following vulnerability has been resolved: net: atlantic: eliminate double free in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: atlantic: elimina double free en la lógica de manejo de errores El controlador tiene una fuga lógica en la asignación de datos del anillo/free, donde se podría llamar a aq_ring_free varias veces en el mismo anillo, si el sistema está bajo estrés y obtuve un error de asignación de memoria. Se utilizó un puntero de anillo como indicador de error, pero esto no es correcto ya que solo se asignan/desasignan datos de anillo. El anillo en sí es un miembro de la matriz. Cambiar las funciones de asignación de anillos para devolver el código de error directamente. • https://git.kernel.org/stable/c/0edb3ae8bfa31cd544b0c195bdec00e036002b5d https://git.kernel.org/stable/c/c11a870a73a3bc4cc7df6dd877a45b181795fcbf https://git.kernel.org/stable/c/d1fde4a7e1dcc4d49cce285107a7a43c3030878d https://git.kernel.org/stable/c/b3cb7a830a24527877b0bc900b9bd74a96aea928 •
