kernel: use-after-free in fs/xfs/xfs_super.c

A flaw was found in the Linux kernel's implementation of the XFS filesystem. A key data structure sb-sfsinfo may not be de-allocated when the system is under memory pressure. This same data structure is then used at a later time during filesystem operations. This could allow a local attacker who ...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the uverbs API. A local user with access to a...

macOS XNU - Copy-on-Write Behavior Bypass via Mount of User-Owned Filesystem Image

XNU has various interfaces that permit creating copy-on-write copies of data between processes, including out-of-line message descriptors in mach messages. It is important that the copied memory is protected against later modifications by the source process; otherwise, the source process might be...

x86: Long latency populate-on-demand operation is not preemptible

ISSUE DESCRIPTION When running an HVM domain in Populate-on-Demand mode, Xen would sometimes search the domain for memory to reclaim, in response to demands for population of other pages in the same domain. This search runs without preemption. The guest can, by suitable arrangement of its memory...
