Astra Linux – Vulnerability in Linux 5.15

A null pointer dereference issue was detected in the can protocol in the net/can/afcan.c file in Linux before Linux. The mlpriv variable may not be initialized in the receive path of CAN frames. A local user could exploit this flaw to crash the system or potentially cause a denial of service...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

There is a speculative pointer dereferencing issue in the Linux kernel, specifically with the doprlimit function. The value of the resource argument is controlled and is used in pointer arithmetic for the ‘rlim’ variable. This can lead to the leakage of its contents. We recommend upgrading to a...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: tpm: efi: Use a local variable to calculate the final log size When tpmreadlogefi is called multiple times, which occurs when one loads and unloads a TPM2 driver multiple times, the global variable efitpmfinallogsize will...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc-bus: Fixed a use-after-free issue in fslmcbusremove. In fslmcbusRemove, mc-rootmcbusdev-mcio was passed to fsldestroymcio. However, mc-rootmcbusdev was already freed in fslmcDeviceRemove. As a result, referencing...

Astra Linux – Vulnerability in nss

During ECDSA signature generation, padding is applied in the nonce to ensure that constant-time scalar multiplication is removed. However, this results in variable-time execution that depends on secret data. This vulnerability affects Firefox versions less than 80, as well as Firefox for Android...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: iommu/omap: Fixed buffer overflow in debugfs There are two issues here: 1 The “len” variable needs to be checked before the very first write. Otherwise, if omap2iommudumpctx is called with “bytes” less than 32, it will result ...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed an out-of-bounds access in rpage. When PAGESIZE is 64K, if logreadrst calls readlogpage for the first time, the size of buffer will be equal to DefaultLogPageSize4K. However, for buffer operations like memcpy, if...

In the Linux kernel, the following vulnerabilities have been resolved: Staging: rtl8712: fixed an issue with uninit-value in usbread8 and related functions. When r8712usbctrlvendorreq returns a negative value, the “data” stored in usbread8,16,32 will not be initialized. Bug: KMSAN: uninit-value i...

Astra Linux – Vulnerability in Qemu

A stack-based buffer overflow was discovered in the virtio-net device of QEMU. This issue occurs when flushing the TX operation in the virtionetflushtx function, provided that the guest has enabled VIRTIONETFHASHREPORT, VIRTIOFVERSION1, and VIRTIONETFMRGRXBUF. This could allow a malicious user to...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

Astra Linux – Vulnerability in grub2

A out-of-bounds read flaw was discovered in Grub2’s NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack can result in sensitive data cached in memory or EFI variabl...

Astra Linux – Vulnerability in dcmtk

DCMTK’s version 3.6.6 does not handle memory release properly. The memory allocated for storing all file information is stored in a global variable called LST, and this memory is not released properly. Making specific requests to the dcmqrdb program can lead to a memory leak. An attacker can use...
