Astra Linux – Vulnerability in 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 the event of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: jbd2: fixed a potential use-after-free issue in jbd2fcwaitbufs. In jbd2fcwaitbufs, using bh after referencing the buffer’s head count may lead to a use-after-free. Therefore, ensure that the buffer is updated before referencing i...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: aead,cipher – The key buffer is zeroed after use. I.G 9.7.B for FIPS 140-3 specifies that variables temporarily holding cryptographic information should be zeroed once they are no longer needed. This is achieved by using...

Astra Linux – Vulnerability in glib2.0

A issue was discovered in GNOME GLib before versions 2.66.7 and 2.67.x before version 2.67.4. If the gbytearraynewtake function was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2^32, resulting in unintended length truncation...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. This flaw allows a malicious guest driver to execute hardware commands when shared buffers have not yet been allocated, potentially leading to a use-after-free condition...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Calling the OpenSSL API function SSLfreebuffers may cause memory to be accessed that was previously freed in some situations. Impact summary: Using memory that has already been freed can lead to various potential consequences, such as corruption of valid data, crashes, or execution...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xsk: fixed an integer overflow in xpcreateandassignumem Since the i and pool-chunksize variables are of type ‘u32’, their product can wrap around and then be cast to ‘u64’. This can result in two different XDP buffers pointing to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fs/buffer: An alert is added in trytofreebuffers for folios without buffers. trytofreebuffers can be called on folios with no buffers attached when filemapreleasefolio is invoked on a folio that belongs to a mapping, and...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: wan/fslucchdlc: Fixed the dmafreecoherent function in uhdlcmemclean. The priv-rxbuffer and priv-txbuffer are allocated together as contiguous buffers in uhdlcinit, but they are freed as two separate buffers in uhdlcmemclean...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp – Use kzalloc for sev ioctl interfaces to prevent kernel memory leaks. For some sev ioctl interfaces, input data may be less than or equal to SEVFWBLOBMAXSIZE, but larger than the data returned by the PSP firmware. In...
