Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/9p: A dedicated spinlock is used for transfd. I'm shamelessly copying the explanation from Tetsuo Handa’s suggested patch1 slightly reworded: syzbot reports inconsistent lock states in p9reqput2. For p9tagremove, when execute...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda: Fixed a potential buffer overflow issue caused by snprintf. The snprintf function returns the size of the string that would be filled if it exceeds the given buffer size. Therefore, using this value may lea...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/restrack: The MR restrack must be released when it is deleted. The MR restrack also needs to be released when it is deleted; otherwise, a memory leak may occur, as the task struct will not be released...

A protection mechanism failure in some third- and fourth-generation IntelR XeonR processors, when using IntelR SGX or IntelR TDX, may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in GnuTLS. This vulnerability allows for a denial of service attack through excessive CPU usage and memory consumption, caused by specially crafted malicious certificates that contain a large number of name constraints and Subject Alternative Names SANs...

Astra Linux – Vulnerability in Golang-1.23

During the resumption of a session in cryptography/TLS, if the underlying Config has its ClientCAs or RootCAs fields changed between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This can occur when a user calls Config.Clone and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validating rxhashkeylen Sashiko points out that rxhashkeylen comes from a uAPI structure and is blindly passed to memcpy, allowing the user space to corrupt kernel memory. A bounds check is performed to prevent memcpy...

Astra Linux – Vulnerability in mbedtls

The use of a broken or risky cryptographic algorithm in the function mbedtlsmpiexpmod in lignum.c in Mbed TLS for all versions prior to 3.0.0, 2.27.0, or 2.16.11 allows attackers with access to precise timing and memory access information typically from an untrusted operating system attacking a...

Astra Linux – Vulnerability in iproute2

In iproute2 before version 5.1.0, there is a use-after-free issue in the getnetnsidfromname function in the ip/ipnetns.c file. NOTE: The relevance of this issue to security may be limited to certain uses of setuid, which, although not a default option, are sometimes an optional configuration...

Astra Linux – Vulnerability in edk2

EDK2’s Network Package is vulnerable to a predictable TCP Initial Sequence Number. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of confidentiality...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s KVM module. This flaw can lead to a denial of service in the x86emulateinsn function in arch/x86/kvm/emulate.c. The flaw occurs when an illegal instruction is executed on the guest CPU of the Intel model...

Astra Linux – Vulnerability in Intel Microcode

Incorrect default permissions in some memory controller configurations for certain IntelR XeonR processors when using IntelR Software Guard Extensions may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in ksmbd within the Linux kernel versions 5.15 through 5.19, prior to 5.19.2. The file fs/ksmbd/smb2misc.c contains an out-of-bounds read and an OOPS error related to the SMB2TREECONNECT function...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...
