CVE-2019-18425

A flaw was in Xen. Guest specified limits for descriptor table access, during PV guest operations, were found to not be enforced. An attacker with the ability to emulate 32-bit guest user mode calls through call gates, would be allowed to install and then use descriptors of their choice as long a...

CVE-2019-18425: Improper Privilege Management

An issue was discovered in Xen through 4.12.x allowing 32-bit PV guest OS users to gain guest OS privileges by installing and using descriptors. There is missing descriptor table limit checking in x86 PV emulation. When emulating certain PV guest operations, descriptor table accesses are performe...

CVE-2011-0182

CVE-2011-0182 affects Apple macOS X kernels prior to 10.6.7, where the i386_set_ldt system call mishandles call gates. The root cause is improper handling of call gate entries, enabling a local attacker to escalate privileges by crafting a malicious call gate entry. The vulnerability yields a loc...

BSD i386_set_ldt syscall does not appropriately validate call gate targets

Overview There are a set of kernel interfaces called "call gates" which are code primitives used to build system-level calls into an operating system's kernel. A subset of these "calls gates" may be able to be manipulated on some operating systems which use improper privilege checking when...
