Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ntfs3: init run lock for extend inode After setting the inode mode of $Extend to a regular file, executing the truncate system call will invoke the dotruncate routine, resulting in an uninitialized runlock error reported by syzbo...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: gfs2: Fix for fiemap page faults In gfs2fiemap, we call iomapfiemap while holding the inode lock. This can lead to recursive locking if the fiemap buffer is memory-mapped to the same inode, and accessing it triggers a page...

CVE-2026-64596

CVE-2026-64596 affects the Linux kernel’s libfs handling. The vulnerability stemmed from init_pseudo() not setting SB_I_NOEXEC and SB_I_NODEV by default, allowing path_noexec() to warn when anonymous-inode files were mmap’d from certain superblocks. The fix sets both flags by default for every ps...

kernel: procfs: avoid fetching build ID while holding VMA lock

A deadlock vulnerability was found in the procfs PROCMAPQUERY ioctl handler. When fetching the optional build ID while holding the VMA lock mmaplock, a circular lock dependency can occur with the inode mutex, causing a system deadlock...

CVE-2026-64323

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A local attacker could craft a malicious UDF image with a specially formed Virtual Allocation Table VAT header. When this image is mounted, the kernel fails to properly validate the VAT header length against the VAT inod...

CVE-2026-64391

A flaw was found in ksmbd, the in-kernel Server Message Block SMB daemon. This vulnerability allows a remote attacker to bypass security restrictions by incorrectly handling credentials for Alternate Data Streams ADS input/output I/O operations. Instead of using the credentials established when t...

CVE-2026-64356

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability occurs during the creation of XFS metadata directories, where a failure in the creation process or a subsequent commit can lead to a memory leak. This leak results in allocated update and transaction state not being properl...

CVE-2026-64378

A flaw was found in the Linux kernel. A race condition exists between the cgroupwritebackumount and inodeswitchwbs functions when a container exits. This race can lead to a kernel panic, resulting in a denial of service. This vulnerability could be triggered by a local user by exiting a container...
