Astra Linux – Vulnerability in Linux, Linux 5.10

A data leak flaw was discovered in the way of the XFSIOCALLOCSP IOCTL in the XFS filesystem, which allows for an increase in file sizes when the size is unaligned. A local attacker could exploit this flaw to leak data from the XFS filesystem that would otherwise be inaccessible to them...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xfs: Save the ailp pointer before releasing the AIL lock during push callbacks. In xfs inodeitempush and xfsqmdquotlogitempush, the AIL lock is released to perform buffer I/O operations. Once the cluster buffer no longer protects...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: filemap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, the folioseekholedata function inadvertently truncated a 64-bit value to 32 bits, which could lead to an infinite loop when writing to an xfs filesystem...

Astra Linux – Vulnerability in Linux, Linux 5.10

A vulnerability was discovered in the fs/inode.c:inodeinitowner function logic of the Linux kernel. This vulnerability allows local users to create files for the XFS file system with unintended group ownership, along with group execution and SGID permission bits set. This occurs in a scenario whe...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iomap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, iomapwritedelallocscan inadvertently used a 32-bit position due to folionextindex returning a unsigned long value. This could lead to an infinite loop when...
