In the Linux kernel, the following vulnerabilities have been resolved: dma: xilinxdpdma: Fixing locking issues There are several places where either chan-lock or chan-vchan.lock was not held. Appropriate locking measures were added. This fixes lockdep warnings such as: 31.077578 ------------ Cut...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, which handles SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the “virtext” field, this issue could all...

Astra Linux – Vulnerability in OpenVSwitch

A flaw was discovered in Open vSwitch, where multiple versions are vulnerable to crafted Geneve packets, which may lead to a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled...

Astra Linux – Vulnerability in libmysofa

Incorrect handling of input data in the loudness function of the libmysofa library in versions 0.5 to 1.1 can lead to heap buffer overflows and access to unallocated memory blocks...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw in the boot CPU could be exploited by attacks targeting speculative execution behavior. This flaw is related to the power management options in the Linux kernel’s X86 CPU. It was discovered in the way users resume the CPU from suspend-to-RAM. A local user could utilize this flaw to...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: riscv/kprobe: Fixed instruction simulation for JALR. Setting kprobe at ‘jalr 1140ra’ in vfswrite results in the following crash’: 32.092235 Unable to handle kernel access to user memory without uaccess routines at virtual address...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fixed the incorrect order of resource deallocation. When attempting to destroy a QP or CQ, we first reduce the reference count and potentially free the memory regions allocated for the object. Then, we request the devic...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A flaw was discovered in the udmabuf device driver of the Linux kernel, within a fault handler. This issue arises due to the lack of proper validation of user-supplied data, which can lead to memory access beyond the end of an array. This may allow an attacker to escalate privileges and execute...

Astra Linux – Vulnerability in xorg-server

A flaw related to out-of-bounds memory access was discovered in the X.Org server. This issue can occur when a device that has been frozen by a sync operation is reattached to a different master device.
