Astra Linux – Vulnerability in Samba

A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions, when the Samba VFS module “aclxattr” is configured with “aclxattr:ignore system acls = yes”. The SMB protocol allows opening files when the client requests read-only...

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: ext4: xattr: fixed a null pointer dereference in ext4raw inode If ext4getinodeloc fails e.g., if it returns -EFSCORRUPTED, iloc.bh will remain set to NULL. Since ext4xattr inodedecrefall lacks error checking, this will lead to a...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

A flaw was discovered in the parsing of extended attributes in the kernel’s ksmbd module. The issue arises due to the lack of proper validation of user-provided data, which can lead to data being read beyond the end of an allocated buffer. An attacker can exploit this vulnerability to disclose...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A use-after-free vulnerability was discovered in the Linux kernel’s ext4 file system, particularly regarding the handling of the additional inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors...

Astra Linux – Vulnerability in Linux 6.1

On Ubuntu kernels that carry both c914c0e27eb0 and “UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs. xattrs”, a non-privileged user may set privileged extended attributes on mounted files, causing those attributes to be applied to the upper files without the appropriate...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ocfs2: Added bounds checking to ocfs2xattrfindentry. A paranoia check was also added to ensure that the function does not stray beyond the valid memory region containing ocfs2 xattr entries during the search for matches. This wil...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Corrected the incorrect validation of the next buffer length in smb2setea. There are multiple smb2eainfo buffers in the FILEFULLEAINFORMATION request from the client. ksmbd uses the NextEntryOffset of the current...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: capabilities: Fixed a potential memory leak on the error path from vfsgetxattralloc. In capinodegetsecurity, we will use vfsgetxattralloc to complete the memory allocation of tmpbuf. If we have completed the memory allocation of...

SUSE CVE-2026-53799

rsync before 3.5.0 contains a symlink race condition vulnerability that allows local attackers to cause rsync to apply arbitrary ACLs or extended attributes to unintended files by substituting a symlink at a predictable destination path between the file write and the subsequent aclsetfile or...

CVE-2026-74414

In the Linux kernel, the following vulnerability has been resolved: hfsplus: Remove the duplicate attr inode dirty marking action Syzbot reported a null-ptr-deref in 1. If the attributes file is not loaded during system mount, a trigger occurs 1 when setxattr is executed in userspace. Remove the...

CVE-2026-74414

CVE-2026-74414 affects the Linux kernel (hfsplus) where a null-pointer dereference could occur during setxattr if the attributes file is not loaded at mount time. The root cause is a duplicate attr inode dirty-marking action in hfsplus/xattr.c, leading to a potential dereference in hfsplus_setxat...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via the process of applying ACLs or extended attributes. An attacker can modify file permissions or attributes of unintended files by exploiting a timing window to substitute a symlink at a predictable destination path...
