Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fixed the duplicated IWCMEVENTCONNECTREPLY event reported. If siwrecvmparr returns -EAGAIN, it means that the MPA reply has not been fully received, and IWCMEVENTCONNECTREPLY should not be reported in this case. This ma...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: spi: bcm2835: bcm2835spihandleerr: Fixed the issue of NULL pointer dereferencing for non-DMA transfers. If an IRQ-based transfer times out, the bcm2835spihandleerr function is called. Since commit 1513ceee70f2 “spi: bcm2835: Drop...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Tracing: Fixed wild-memory-access in registersynthevent. In registersynthevent, if setsyntheventprintfmt fails, then both traceremoveeventcall and unregisterTraceEvent will be called. This means that traceeventcall will call...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: safexcel – Added error handling for dmamapsg calls. The macro dmamapsg function may return 0 in case of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are unmappe...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: lantiq – Fix for memory corruption in the RX ring. In situations where memory allocation or DMA mapping fails, an invalid address may be programmed into the descriptor. This can lead to memory corruption. If memory allocatio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dma-debug: prevents an error message from causing runtime problems. For some drivers that use the DMA API, this error message can occur several million times per second. This can lead to excessive use of the kernel’s printk buffe...

Astra Linux – Vulnerability in Xen

A issue was discovered in Xen through version 4.11.x, allowing users of x86 Intel HVM guest operating systems to obtain unintended read/write DMA access. This could potentially lead to a denial of service host operating system crash or privilege escalation. This issue arises because a backport...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the fs/f2fs/node.c file within the f2fs module of the Linux kernel, in versions prior to 5.12.0-rc4. A failure in the bounds check allows a local attacker to gain access to out-of-bounds memory, resulting in a system crash or the leakage of...

Astra Linux – Vulnerability in Chromium

Memory access out of bounds in V8 in Google Chrome prior to 98.0.4758.80 allowed a remote attacker to potentially exploit heap corruption through a crafted HTML page...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: fs/ntfs3: Return error for inconsistent extended attributes The ntfsreadea function is called when we want to read extended attributes. There are some sanity checks for the validity of these attributes. However, it fails to...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, responsible for supporting SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest, which is used to spawn or handle a nested guest L2. Due to improper validation of the...
