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: 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 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

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 – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Support for specifying the srptserviceguid parameter. The current behavior is that setting this parameter while loading the ibsrpt kernel module triggers a kernel crash. BUG: Kernel NULL pointer dereferencing, address:...

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...
