‘Sinkclose’ Flaw in Hundreds of Millions of AMD Chips Allows Deep, Virtually Unfixable Infections

Researchers warn that a bug in AMD’s chips would allow attackers to root into some of the most privileged portions of a computer—and that it has persisted in the company’s processors for decades...

USN-6952-1: Linux kernel vulnerabilities

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to...

AMD CPUs -- Guest Memory Vulnerabilities

AMD reports: Researchers from IOActive have reported that it may be possible for an attacker with ring 0 access to modify the configuration of System Management Mode SMM even when SMM Lock is enabled. Improper validation in a model specific register MSR could allow a malicious program with ring0...

SMM Lock Bypass

AMD ID: AMD-SB-7014 Potential Impact: Arbitrary Code Execution Severity: High Summary Researchers from IOActive have reported that it may be possible for an attacker with ring 0 access to modify the configuration of System Management Mode SMM even when SMM Lock is enabled...

"The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6952-1 advisory. Benedict Schlter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious VC interrupts and...

kernel: net: amd-xgbe: Fix skb data length underflow

In the Linux kernel, the following vulnerability has been resolved: net: amd-xgbe: Fix skb data length underflow There will be BUGON triggered in include/linux/skbuff.h leading to intermittent kernel panic, when the skb length underflow is detected. Fix this by dropping the packet if such length...

kernel: use-after-free in kv_parse_power_table

A use-after-free flaw was found in kvparsepowertable in drivers/amd/pm in the Linux kernel. When ps equals NULL, kvparsepowertable frees adev-pm.dpm.ps. The adev-pm.dpm.ps is used in the loop of kvdpmfini after its first free in kvparsepowertable, causing a use-after-free problem...

The vulnerability of the gfx_v9_4_3_init_microcode() driver for AMDGPU cores in the Linux operating system allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the gfxv943initmicrocode function in the drivers/gpu/drm/amd/amdgpu/gfxv943.c driver for the AMD GPU in the Linux operating system is related to memory writing beyond the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality...

SUSE CVE-2024-42118

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Do not return negative stream id for array WHY resourcestreamtostreamidx returns an array index and it return -1 when not found; however, -1 is not a valid array index number. HOW When this happens, call ASSERT,...

SUSE CVE-2024-42119

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Skip finding free audio for unknown engineid WHY ENGINEIDUNKNOWN = -1 and can not be used as an array index. Plus, it also means it is uninitialized and does not need free audio. HOW Skip and return NULL. This...

SUSE CVE-2024-42121

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check index msgid before read or write WHAT msgid is used as an array index and it cannot be a negative value, and therefore cannot be equal to MODHDCPMESSAGEIDINVALID -1. HOW Check whether msgid is valid before...
