In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: Fixed an issue where the nftcountersenabled counter might underflow during the nftablesaddchain function. The syzbot reports that the nftcountersenabled counter might underflow at nftablesaddchain1. The issue...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftables – A possible module reference underflow in the error path. The dst-ops field is set when nftexprclone fails, but the module reference count has not been updated yet. As a result, nftexprdestroy causes a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: ipa: Hash tables are only reset when supported. Last year, the code that manages GSI channel transactions switched from using spinlock-protected linked lists to using indexes in the ring buffer used for a channel. Recently,...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, and Linux 5.10

A use-after-free vulnerability in the Linux kernel’s netfilter:nftables component can be exploited to achieve local privilege escalation. Adding or removing rules from chain bindings within the same transaction can lead to use-after-free issues. We recommend upgrading to the version after the...

Astra Linux – Vulnerability in Linux, Linux 5.10

The file net/netfilter/nfdupnetdev.c in the Linux kernel versions 5.4 through 5.6.10 allows local users to gain privileges due to a heap-out-of-bounds write. This issue is related to the nftablesoffload mechanism...

Astra Linux – Vulnerability in grub2

A heap out-of-bounds write may occur during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. The impacts on confidentiality, integrity, and availability are considered low, as it is very complex for an attacker to control the encoding and...
