Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Allow AppArmor to handle unaligned DFA tables. DFA tables can originate from the kernel or user space, and 8-byte alignment is not always guaranteed. This may lead to unaligned memory accesses on various architectures...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Fixed the race condition between freeing data and accessing it through the file system. AppArmor originally placed a reference to private data after removing the original entry from the file system. However, the inode m...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix side-effect bug in matchchar macro usage The matchchar macro evaluates its character parameter multiple times when traversing differential encoding chains. When invoked with str++, the string pointer advances on eac...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: AppArmor: Fixed and optimized the creation of tables from potentially unaligned memory. The source code may come from user space, and it might be unaligned. Try to optimize the copying process by avoiding unaligned memory...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Avoid per-cpu hold underflow in aagetbuffer. When aagetbuffer retrieves data from the per-cpu list, it conditionally decrements cache-hold. If hold reaches 0 while count remains non-zero, the unsigned decrement wraps to...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: It is ensured that the DFA start states are within the valid range when unpackpdb is called. The start states are read from untrusted data and used as indexes into the DFA state tables. The aadfanext function call in...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Fixed a race condition related to the dereference of rawdata objects. There is a race condition that leads to a “use-after-free” situation: Since the rawdata inodes are not counted for their references, an attacker can...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: AppArmor: Fixing differential encoding verification Differential encoding allows loops to be created if it is abused. To prevent this, the unpacking process should verify that the diff-encode chain terminates. Unfortunately, t...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: The recursive approach used for removing profiles has been replaced with an iterative one. The profile removal code uses recursion when removing nested profiles, which can lead to kernel stack exhaustion and system...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: AppArmor: Fixed the issue where an unprivileged local user could perform privileged policy management. An unprivileged local user can load, replace, and remove policies by opening the AppArmor interfaces. This can be achieved...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: A memory leak was fixed in the verifyheader function. The function sets ns = NULL on every call, causing a memory leak for the namespace string allocated in previous iterations when multiple profiles are unpacked. This...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Fixed the issue by limiting the number of levels of policy namespaces. Currently, the number of policy namespaces is not bounded, as it relies on the user namespace limits. However, policy namespaces are not strictly ti...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Apparmor: Fixed a missing bounds check on the DEFAULT table in verifydfa. The verifydfa function only checks the bounds of DEFAULTTABLE when the state is not differentially encoded. When the verification loop traverses the...
