https://notcve.org/view.php?id=CVE-2023-52669
In the Linux kernel, the following vulnerability has been resolved: crypto: s390/aes - Fix buffer overread in CTR mode When processing the last block, the s390 ctr code will always read a whole block, even if there isn't a whole block of data left. Fix this by using the actual length left and copy it into a buffer first for processing. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: s390/aes - Corrige la sobrelectura del buffer en modo CTR Al procesar el último bloque, el código ctr s390 siempre leerá un bloque completo, incluso si no hay un bloque completo de datos restantes. Solucione este problema utilizando la longitud real restante y cópielo primero en un búfer para procesarlo. • https://git.kernel.org/stable/c/0200f3ecc19660bebeabbcbaf212957fcf1dbf8f https://git.kernel.org/stable/c/cd51e26a3b89706beec64f2d8296cfb1c34e0c79 https://git.kernel.org/stable/c/a7f580cdb42ec3d53bbb7c4e4335a98423703285 https://git.kernel.org/stable/c/dbc9a791a70ea47be9f2acf251700fe254a2ab23 https://git.kernel.org/stable/c/d68ac38895e84446848b7647ab9458d54cacba3e https://git.kernel.org/stable/c/e78f1a43e72daf77705ad5b9946de66fc708b874 https://git.kernel.org/stable/c/d07f951903fa9922c375b8ab1ce81b18a0034e3b https://lists.debian.org/debian-lts-announce/2024/06/ •

CVSS: 5.5EPSS: 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 https://access.redhat.com/security/cve/CVE-2023-52664 https://bugzilla.redhat.com/show_bug.cgi?id=2281356 •
