  3. CVE-2024-50208
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages Avoid memory corruption while setting up Level-2 PBL pages for the non MR resources when num_pages > 256K. There will be a single PDE page address (contiguous pages in the case of > PAGE_SIZE), but, current logic assumes multiple pages, leading to invalid memory access after 256K PBL entries in the PDE.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/bnxt_re: Se corrige un error al configurar páginas PBL de nivel 2 Evita la corrupción de memoria al configurar páginas PBL de nivel 2 para los recursos que no son MR cuando num_pages > 256K. Habrá una única dirección de página PDE (páginas contiguas en el caso de > PAGE_SIZE), pero la lógica actual supone varias páginas, lo que genera un acceso a memoria no válido después de 256K entradas PBL en el PDE.
