Astra Linux – Vulnerability in Wayland

An internal reference count is maintained on the buffer pool; this count increments every time a new buffer is created from the pool. The reference count is stored as an integer. On LP64 systems, this can lead to an overflow if the client creates a large number of wlshm buffer objects, or if it...

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Fixed a reference count leak in aapivotroot. The aapivotroot function has a reference counting bug in a specific path. When aareplacecurrentlabel returns successfully, the function forgets to decrement the reference cou...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: core – Ensure that the LLD module reference count is set after the SCSI device is released. The SCSI host release is triggered when the SCSI device is freed. We must ensure that the low-level device driver module is not...

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix race condition between ipv6getifaddr and ipv6deladdr Although ipv6getifaddr walks inet6addrlst under the RCU lock, it still means hlistforeachentryrcu can return an item that got removed from the list. The memory itself...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: A possible reference count leak in smb2open has been fixed. The reference count of ACLs will cause a leak when memory allocation fails. This issue has been addressed by adding the missing posixaclrelease function...

Astra Linux – Vulnerability in ujson

UltraJSON is a fast JSON encoder and decoder written in pure C, with bindings for Python 3.7+. Before version 5.12.1, when the ujsondump function wrote to a file-like object, and the write operation raised an exception, the serialized JSON string object was not decremented, resulting in memory...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The reference count leak in smbcheckpermdacl has been fixed. The issue occurs in a specific part of smbcheckpermdacl. When “id” and “uid” have the same value, the function simply jumps out of the loop without decrementing...

Astra Linux – Vulnerability in Firefox and Thunderbird

If an AlignedBuffer is assigned to itself, the subsequent self-move operation may lead to an incorrect reference count, potentially causing a use-after-free issue. This vulnerability affects Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fixed the incorrect order of resource deallocation. When attempting to destroy a QP or CQ, we first reduce the reference count and potentially free the memory regions allocated for the object. Then, we request the devic...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fixed the mpolnew leak in sharedpolicyreplace. If mpolnew is allocated but not used during the restart loop, mpolnew will be freed via mpolput before returning to the caller. However, refcnt has not been initialized...

Astra Linux – Vulnerability in Linux 5.10

A flaw was discovered in btrfsgetrootref in fs/btrfs/disk-io.c within the btrfs filesystem of the Linux kernel, due to a double decrement of the reference count. This issue may allow a local attacker with user privileges to crash the system or may lead to the leakage of internal kernel informatio...
