Astra Linux – Vulnerability in commons-io

In Apache Commons IO before version 2.7, when the FileNameUtils.normalize method was called with an improper input string, such as “//../foo” or “\..\foo”, the result would be the same value. This potentially allowed access to files in the parent directory, but not further up the path thus...

Astra Linux – Vulnerability in Linux 5.10

Due to a vulnerability in the iouring subsystem, it is possible for kernel memory information to be leaked to the user process. timensinstall calls currentissinglethreaded to determine whether the current process is single-threaded. However, this call does not take into account iouring’s ioworker...

Astra Linux – Vulnerability in CGal

There are multiple code execution vulnerabilities in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. A specially crafted, malformed file can lead to an out-of-bounds read and type confusion, which may result in code execution. An attacker can provide malicious input to trigger a...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw in the Linux kernel was discovered in the i740 driver. The userspace program can pass any value to the driver through the ioctl interface. The driver does not check the value of ‘pixclock’, which may lead to a division by zero error...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: gadgetfs: epio – wait until IRQ finishes. After usbepqueue, if waitforcompletioninterruptible is interrupted, we need to wait until IRQ is completed. Otherwise, complete from epiocomplete can corrupt the stack...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: The ioaw hook was defined as mmiowb. The commit fb24ea52f78e0d595852e states that “drivers: Explicit invocations of mmiowb were removed.” All occurrences of mmiowb in drivers were removed. However, it is noted that:...

The btsockrecvmsg function in net/bluetooth/afbluetooth.c in the Linux kernel, as of version 6.6.8, has a use-after-free issue due to a race condition involving btsockioctl...

Astra Linux – Vulnerability in Qemu

A reentrancy issue with DMA was discovered in the Tulip device emulation in QEMU. When Tulip reads from or writes to the rx/tx descriptor, or copies the rx/tx frame, it does not check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drbd: fixed the “LOGIC BUG” in drbdalbeginiononblock Although we ensure that we can perform lcgetcumulative while holding the device-allock spinlock, it may still fail if some other code path decides to use lctrylock at the wrong...

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

In the Linux kernel, the following vulnerability has been resolved: fbdev: sis: An error will occur if pixclock equals zero. The user-space program can pass any values to the driver through the ioctl interface. If the driver does not check the value of pixclock, it may lead to a divide-by-zero...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: x86/tdx: Fixed the “in-kernel MMIO” check TDX only supports MMIO operations initiated by the kernel. The handlemmio function checks whether the VE exception occurred in the kernel and rejects the operation if it did. However,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ublkdrv: A NULL pointer dereference issue was fixed in ublkctrlstartrecovery. When two UBLKCMDSTARTUSERRECOVERY commands are submitted, the first one sets ‘ubq-ubqdaemon’ to NULL, and the second one triggers a WARN in...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: The IORINGOPREAD function did not correctly handle the provided buffer list when the read I/O operation returned a value less than 0 except for the -EAGAIN and -EIOCBQUEUED returns. This could lead to a potential “use-after-free”...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: Memory: fslifc: fixed the issue of leaking the IO mapping during probe failures. During probe errors, the driver should unmap the IO memory. Match report: drivers/memory/fslifc.c:298 fslifcctrlprobe warning:...
