FreeBSD -- ICMPv6 / MLDv2 out-of-bounds memory access

Problem Description: The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. Impact: A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page a...

Privilege Escalation

kernel is vulnerable to privilege escalation. A use-after-free in the svcprocesscommon function allows an attacker to cause a host kernel memory corruption and a system panic, potentially resulting in a successful privilege escalation...

CVE-2019-13648

A flaw was found in the PowerPc platform, where the kernel will panic if the transactional memory is disabled. An attacker could use this flaw to panic the system by constructing a signal context through the transactional memory MSR bits set...

DEBIAN-CVE-2018-16871

A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to...

kernel: nfs: use-after-free in svc_process_common()

A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bcsvcprocess use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and ...
