DEBIAN-CVE-2017-1000405

The Linux Kernel versions 2.6.38 through 4.14 have a problematic use of pmdmkdirty in the touchpmd function inside the THP implementation. touchpmd can be reached by getuserpages. In such case, the pmd will become dirty. This scenario breaks the new canfollowwritepmd's logic - pmd can become dirt...

kernel: uninit op in SOCKOPS_WRAP() leads to privesc

The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in protoops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on...
