Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix for double execution of the request. If a netfs request completes during the pause loop, the reference belonging to the INPROGRESS flag will be removed at that point. However, if the request proceeds to the final wait...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: s390: fixed the issue where double-free of GS and RI CBs occurs during fork failures. The pointers for guarded storage and runtime instrumentation control blocks are stored in the threadstruct of the associated task. These...

Astra Linux – Vulnerability in Linux 5.10

A double-free flaw was discovered in the Linux kernel’s TUN/TAP device driver functionality, particularly in how a user registers the device when the registernetdevice function fails with the NETDEVREGISTER notifier. This flaw allows a local user to crash the system or potentially escalate their...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: NFSv4.2: Rework the handling of scratch space for READPLUS again. I found that the read code might send multiple requests using the same nfspgioheader. However, the nfs4procreadsetup function is only called once. As a result, we...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drm/panfrost: Fixed corruption of the shrinker list caused by the madvise IOCTL. Calling the madvise IOCTL twice on BO causes corruption of the memory shrinker list, leading to a kernel crash. This occurs because BO is already on...

Astra Linux – Vulnerability in bluez

In BlueZ before version 5.55, a double-free error was detected in the gatttool disconnectcb routine from the shared/att.c file. A remote attacker could potentially cause a denial of service or code execution during service discovery, due to the redundant disconnect MGMT event...

Astra Linux – Vulnerability in openjpeg2

In OpenJPEG version 2.3.1, the jp2/opjdecompress.c file contains a use-after-free issue. This issue can occur if there is a mix of valid and invalid files in a directory that is processed by the decompressor. It is also possible for a double free to occur. This issue is related to calling...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: zstd – fix double-free in per-CPU stream cleanup The crypto/zstd module contains a double-free bug that occurs when multiple tfms are allocated and freed. The issue arises because the zstdstreams per-CPU contexts are free...

Astra Linux – Vulnerability in Linux 5.10, Linux

A use-after-free flaw was discovered in vhostnetsetbackend in drivers/vhost/net.c within the virtio network subcomponent of the Linux kernel, due to a double fget operation. This flaw could allow a local attacker to cause the system to crash, and could even lead to a kernel information leak issue...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mac80211: A potential double-free operation occurred during mesh join. While commit 6a01afcf8468 “mac80211: Mesh: Deleting ie data when leaving the mesh” fixed a memory leak that occurred during mesh leave/teardown, it introduced...

Astra Linux – Vulnerability in libxml2

A issue was discovered in libxml2 before version 2.10.4. When hashing empty dictionary strings in a crafted XML document, the xmlDictComputeFastKey function in dict.c can produce non-deterministic values, resulting in various logical and memory errors, such as double-free errors. This behavior...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfsd: calls oprelease, even when opfunc returns an error. For operations with “trivial” responses, nfsd4encodeoperation will shortcut most of the encoding process and simply perform marshaling of the status. One of the things it...

Astra Linux – Vulnerability in the 389-DS-base

A double-free was detected in the way that 389-ds-base handles virtual attribute contexts during persistent searches. An attacker could send a series of search requests, causing the server to behave unexpectedly and potentially crashing it...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: dsa: Unnecessary ofnodeput function removed from felixParseportsnode. The unnecessary ofnodeput function was removed from the continue path to prevent a child node from being released twice, which could lead to resource leak...

Astra Linux – Vulnerability in Linux 5.10

A double-free bug in the packetsetring function in net/packet/afpacket.c can be exploited by a local user through crafted syscalls to escalate privileges or deny services. We recommend upgrading the kernel to a version that is not affected by this bug, or rebuilding the code after the...

Astra Linux – Vulnerability in dcmtk

DCMTK through version 3.6.6 does not handle memory deallocation properly. The object in the program is freed, but its address is still used in other locations. Sending specific requests to the dcmqrdb program will lead to a double-free. An attacker can use this vulnerability to launch a DoS attac...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: pmf: Use device-managed allocations. If setting up smart PC fails for any reason, it can lead to a double-free when unloading amd-pmf. This occurs because dev-buf was freed but never set to NULL, and then...

Astra Linux – Vulnerability in Linux, Linux 5.10

The function usb8devstartxmit in the file drivers/net/can/usb/usb8dev.c within the Linux kernel, up to version 5.17.1, contains a double-free...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: mt7622-apmixedsys: Fixed an error handling path in clkmt8135apmixedprobe. The clkdata is allocated using mtkdevmallocclkdata. Therefore, explicitly calling mtkfreeclkdata in the removal function would lead to a...
