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

In the Linux kernel, the following vulnerability has been resolved: ext4: Detecting invalid INLINEDATA + EXTENTS flag combinations Syzbot reported a bug in ext4escacheextent when opening a Verity file on a corrupted ext4 file system that was mounted without a journal. The issue arises when the fi...

Astra Linux – Vulnerability in Linux 5.10, Linux

Dm-verity is used to extend the root-of-trust to root file systems. LoadPin builds upon this feature to restrict module/firmware loads to only the trusted root file system. Currently, device-mapper table reloads allow users with root privileges to replace the target with an equivalent dm-linear...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: dm-verity: Recursive forward error correction has been disabled. There are two issues with this recursive correction mechanism: 1. It may cause a denial-of-service attack. In the fecreadbufs function, there is a loop with 253...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the context of dm-verity-target.c, there is a potential way to modify read-only files due to a missing permission check. This could lead to a local escalation of privileges, as System execution privileges are required. User interaction is not necessary for exploiting this vulnerability. Produc...

kernel: dm-verity: fix buffer overflow in FEC calculation

A flaw was found in the dm-verity component of the Linux kernel. A buffer overflow occurs during Forward Error Correction FEC calculation, allowing an attacker to write past the end of an allocated buffer. This out-of-bounds write can corrupt the syndrome buffer, potentially leading to system...
