Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates from allowing leakage of DMA mapping entries...

UBUNTU-CVE-2021-46920

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix clobbering of SWERR overflow bit on writeback Current code blindly writes over the SWERR and the OVERFLOW bits. Write back the bits actually read instead so the driver avoids clobbering the OVERFLOW bit that...

Siemens SIMATIC CP products Improper Access Control (CVE-2023-37194)

A vulnerability has been identified in SIMATIC CP 1604 All versions, SIMATIC CP 1616 All versions, SIMATIC CP 1623 All versions, SIMATIC CP 1626 All versions, SIMATIC CP 1628 All versions. The kernel memory of affected devices is exposed to user-mode via direct memory access DMA which could allow...

kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed

A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intelgvtdmamapguestpage function. This issue could allow a local user to crash the system...

QEMU: e1000e: heap use-after-free in e1000e_write_packet_to_guest()

A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service...

kernel: swiotlb information leak with DMA_FROM_DEVICE

A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMAFROMDEVICE. This flaw allows a local user to read random memory from the kernel space...

QEMU: hcd-ehci: DMA reentrancy issue leads to use-after-free

A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions such as reset whi...

Qualcomm Chipsets Security Vulnerability

Qualcomm Chipsets are a family of chipsets from Qualcomm Incorporated USA. A security vulnerability exists in Qualcomm Chipsets due to a memory corruption in the camera when installing fd for a specific DMA buffer...

CVE-2023-29063 Lack of DMA Access Protections

The FACSChorus workstation does not prevent physical access to its PCI express PCIe slots, which could allow a threat actor to insert a PCI card designed for memory capture. A threat actor can then isolate sensitive information such as a BitLocker encryption key from a dump of the workstation RAM...

kernel: i40e: Fix DMA mappings leak

A DMA mapping leak vulnerability was found in the Intel i40e network driver in the Linux kernel. During reallocation of RX buffers when changing ring parameters via ethtool, DMA mappings are not properly cleaned up before creating new ones. Repeated ring size changes can exhaust DMA resources,...

SUSE CVE-2023-6238

A buffer overflow vulnerability was found in the NVM Express NVMe driver in the Linux kernel. Only privileged user could specify a small meta buffer and let the device perform larger Direct Memory Access DMA into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes...
