SUSE CVE-2019-18222

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks...

SUSE CVE-2019-18422

An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service or gain privileges by leveraging the erroneous enabling of interrupts. Interrupts are unconditionally unmasked in exception handlers. When an exception occurs on an ARM system which is handled...

SUSE CVE-2019-18423

An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service via a XENMEMaddtophysmap hypercall. p2m-maxmappedgfn is used by the functions p2mresolvetranslationfault and p2mgetentry to sanity check guest physical frame. The rest of the code in the two...

SUSE CVE-2019-19581

An issue was discovered in Xen through 4.12.x allowing 32-bit Arm guest OS users to cause a denial of service out-of-bounds access because certain bit iteration is mishandled. In a number of places bitmaps are being used by the hypervisor to track certain state. Iteration over all bits involves...

SUSE CVE-2020-6096

An exploitable signed comparison vulnerability exists in the ARMv7 memcpy implementation of GNU glibc 2.30.9000. Calling memcpy on ARMv7 targets that utilize the GNU glibc implementation with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker...

SUSE CVE-2020-10702

A flaw was found in QEMU in the implementation of the Pointer Authentication PAuth support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker...

SUSE CVE-2020-10932

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

SUSE CVE-2020-10941

Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information an RSA private key by measuring cache usage during an import...

SUSE CVE-2020-13844

Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka "straight-line speculation."...

SUSE CVE-2020-15564

An issue was discovered in Xen through 4.13.x, allowing Arm guest OS users to cause a hypervisor crash because of a missing alignment check in VCPUOPregistervcpuinfo. The hypercall VCPUOPregistervcpuinfo is used by a guest to register a shared region with the hypervisor. The region will be mapped...

SUSE CVE-2020-25604

An issue was discovered in Xen through 4.14.x. There is a race condition when migrating timers between x86 HVM vCPUs. When migrating timers of x86 HVM guests between its vCPUs, the locking model used allows for a second vCPU of the same guest also operating on the timers to release a lock that it...

SUSE CVE-2020-29571

An issue was discovered in Xen through 4.14.x. A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered read...

SUSE CVE-2020-36425

An issue was discovered in Arm Mbed TLS before 2.24.0. It incorrectly uses a revocationDate check when deciding whether to honor certificate revocation via a CRL. In some situations, an attacker can exploit this by changing the local clock...

SUSE CVE-2020-36426

An issue was discovered in Arm Mbed TLS before 2.24.0. mbedtlsx509crlparseder has a buffer over-read of one byte...

SUSE CVE-2021-20221

An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to...

SUSE CVE-2021-26933

An issue was discovered in Xen 4.9 through 4.14.x. On Arm, a guest is allowed to control whether memory accesses are bypassing the cache. This means that Xen needs to ensure that all writes such as the ones during scrubbing have reached the memory before handing over the page to a guest...

SUSE CVE-2021-28693

xen/arm: Boot modules are not scrubbed The bootloader will load boot modules e.g. kernel, initramfs... in a temporary area before they are copied by Xen to each domain memory. To ensure sensitive data is not leaked from the modules, Xen must "scrub" them before handing the page over to the...

SUSE CVE-2021-28700

xen/arm: No memory limit for dom0less domUs The dom0less feature allows an administrator to create multiple unprivileged domains directly from Xen. Unfortunately, the memory limit from them is not set. This allow a domain to allocate memory beyond what an administrator originally configured...
