UBUNTU-CVE-2024-56611

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix migratetonode assuming there is at least one VMA in a MM We currently assume that there is at least one VMA in a MM, which isn't true. So we might end up having findvma return NULL, to then de-reference NULL. So...

CVE-2021-47462

CVE-2021-47462 affects the Linux kernel mempolicy/memory policy handling. The root cause was an invalid combination check for MPOL_MODE_FLAGS: MPOL_F_NUMA_BALANCING may only pair with MPOL_BIND, but the check existed only in do_set_mempolicy(). The patch moves this validation into sanitize_mpol_f...
