Linux Kernel Sendpage Local Privilege Escalation

The Linux kernel failed to properly initialize some entries in the protoops struct for several protocols, leading to NULL being dereferenced and used as a function pointer. By using mmap2 to map page 0, an attacker can execute arbitrary code in the context of the kernel. Several public exploits...

Design/Logic Flaw

The vmmaplookup function in sys/vm/vmmap.c in the mmap implementation in the kernel in FreeBSD 9.0 through 9.1-RELEASE-p4 does not properly determine whether a task should have write access to a memory location, which allows local users to bypass filesystem write permissions and consequently gain...
