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 5.10

In the Linux kernel, the following vulnerability has been resolved: HID: Intel-thc-hid: Added a safety check for reading the DMA buffer. A readiness check for the DMA buffer is added before reading it, to avoid unexpected NULL pointer accesses...

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 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...

In the Linux kernel, the following vulnerability has been resolved: net/rds: fixed the possible null dereference of cp The cp parameter may be null. Calling cp-cpconn would result in a null dereference. Simon Horman adds: Analysis: cp is a parameter of rdsrdmamap, and it is not reassigned. The...

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 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

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 Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Initialize freeqp completion before using it. In irdmacreateqp, if ibcopytoudata fails, it will call irdmaDestroyQp to clean up. This process will attempt to wait for the freeqp completion, but freeqp has not yet been...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Misaligned – Restricts user access to kernel memory. The rawcopyto,fromuser function does not call accessok, allowing userspace to access any virtual memory address...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: A potential null-ptr-deref occurred in passestablish. If getepfromtid fails to find a non-NULL value for ep, ep will be dereferenced later, regardless of whether it is empty. This patch adds a simple sanity check to f...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: misc: pciendpointtest: Free IRQs before removing the device. In the pciendpointtestremove function, freeing the IRQs after removing the device creates a small race window during the test process. This allows IRQs to be received b...

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 found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SPI: sun6i – Fixing the race condition between DMA RX transfer completion and RX FIFO drain. Previously, the transfer-completion interrupt would immediately drain the RX FIFO to read any remaining data in the FIFO into the RX...

Astra Linux – Vulnerability in Chromium

In Google Chrome browsers, out-of-bounds memory access in V8 was possible before version 89.0.4389.72. This allowed a remote attacker to potentially perform out-of-bounds memory access through a crafted HTML page...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

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.
