In the Linux kernel, the following vulnerability has been resolved: powerpc/32: Fix hard lockup on vmap stack overflow Since the commit c118c7303ad5 “powerpc/32: Fix vmap stack - Do not activate MMU before reading task struct”, a vmap stack overflow results in a hard lockup. This is because...

Astra Linux – vulnerability in xorg-server

A stack-based buffer overflow vulnerability has been identified in the X.Org X server and Xwayland. An inconsistency between the X server’s maximum allowable length for font names and the libXfont2 library’s limits can lead to a stack buffer overflow during font alias resolution. The server...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: MIPS: Do not crash in stacktop for tasks without ABI or vDSO Not all tasks have an associated ABI or a mapped vDSO; for instance, kthreads never do. If such a task calls stacktop, it will dereference the NULL ABI pointer and cras...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbus/adm1266 Widens the blackbox-info buffer to I2CSMBUSBLOCKMAX. The function adm1266nvmemreadblackbox declares a 5-byte stack buffer and passes it to i2csmbusreadblockdata to retrieve the 4-byte BLACKBOXINFO response...

Astra Linux – vulnerability in nasm

A stack-use-after-scope issue found in the expandmmacparams function within preproc.c in nasm prior to version 2.15.04 enables remote attackers to trigger a denial of service by using a specially crafted asm file...

Astra Linux – vulnerability in nbd

In nbd-server in nbd prior to version 3.24, there is a stack-based buffer overflow. An attacker can trigger a buffer overflow in the parsing of the name field by sending a crafted NBDOPTINFO or NBDOPTGO message containing a large value as the length of the name...

Astra Linux – Vulnerability in libxstream-java

XStream is a simple library for serializing objects to XML and back again. This vulnerability may allow a remote attacker to terminate the application with a stack overflow error, resulting in a denial of service—only by manipulating the processed input stream when XStream is configured to use th...

Astra Linux – Vulnerability in Linux

In the file drivers/pci/hotplug/rpadlpar/sysfs.c within the Linux kernel up to version 5.11.8, the RPA PCI Hotplug driver suffers a user-tolerable buffer overflow when writing a new device name to the driver from user space. This allows user space to write data directly to the kernel stack frame...
