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.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a potential double-free in fs_any_create_groups When kcalloc() for ft->g succeeds but kvzalloc() for in fails, fs_any_create_groups() will free ft->g. However, its caller fs_any_create_table() will free ft->g again through calling mlx5e_destroy_flow_table(), which will lead to a double-free. Fix this by setting ft->g to NULL in fs_any_create_groups(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: corrige una posible double free en fs_any_create_groups Cuando kcalloc() para ft->g tiene éxito pero kvzalloc() para in falla, fs_any_create_groups() liberará ft-> gramo. Sin embargo, su llamador fs_any_create_table() liberará ft->g nuevamente llamando a mlx5e_destroy_flow_table(), lo que conducirá a un double free.
