UBUNTU-CVE-2023-42752
An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating skbsharedinfo in the userspace, which is exploitable in systems without SMAP protection since skbsharedinfo contains references to function pointers...
SUSE CVE-2014-7156
The x86emulate function in arch/x86/x86emulate/x86emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service guest crash via unspecified vectors...
SUSE CVE-2014-7155
The x86emulate function in arch/x86/x86emulate/x86emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service guest crash or gain guest kernel mode privileges via vectors involving an 1 HLT, 2 LGDT, 3 LIDT, or 4...
CVE-2022-0001
A flaw was found in hw. The Branch History Injection BHI describes a specific form of intra-mode BTI. This flaw allows an unprivileged attacker to manipulate the branch history before transitioning to supervisor or VMX root mode. This issue is an effort to cause an indirect branch predictor to...
The vulnerability of the FreeBSD operating system’s kernel, related to deficiencies in the authentication mechanism, allows a perpetrator to disable the SMAP protection and compromise the integrity of the protected information.
The vulnerability of the FreeBSD operating system’s kernel is related to deficiencies in the authentication mechanism. Exploiting this vulnerability allows a malicious actor to disable the SMAP protection and compromise the integrity of the protected information during system calls...
kernel: race conditions caused by wrong locking in net/vmw_vsock/af_vsock.c
A flaw was found in the Linux kernel. Wrong locking in the AFVSOCK socket can cause a local privilege escalation, bypassing SMEP and SMAP. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...
CVE-2016-6259
Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention SMAP whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service hypervisor and VM crash by triggering a safety check...
