Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the ksmbd component of the Linux kernel, a high-performance in-kernel SMB server. The specific flaw exists in the processing of SMB2TREEDISCONNECT commands. The issue arises due to the lack of proper locking when performing operations on an object. An attacker can exploit...

Astra Linux – Vulnerability in Mariadb 10.3

MariaDB Server before version 10.7 is vulnerable to Denial of Service attacks. In the file extra/mariabackup/dscompress.cc, when an error occurs i.e., transitioning to the err label during the execution of the createworkerthreads method, the held lock thd-ctrlmutex is not released properly. This...

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

In the Linux kernel, the following vulnerabilities have been resolved: nvmet: Avoid recursive nvmet-wq flushing in nvmetctrlfree. The nvmettcpreleasequeuework function runs on nvmet-wq and can remove the final controller reference through nvmetcqput. If this triggers nvmetctrlfree, the tear-down...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

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...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/nldev: Fixed issues with locking when accessing mr-pd. Sashiko points out that, due to reregmr, the PD is actually a variable, and all the operations in nldev are volatile. It’s recommended to use mr-device instead of...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: interconnect: Fixed locking issues related to runpm and reclaim. For cases where iccbwset can be called in paths that may lead to deadlocks with shrinker/reclaim, such as during runpm resume, we need to separate the icc lockin...

Astra Linux – Vulnerability in Mariadb 10.3

MariaDB Server before version 10.7 is vulnerable to Denial of Service attacks. In the file extra/mariabackup/dscompress.cc, when an error occurs pthreadcreate returns a non-zero value during the execution of the createworkerthreads method, the held lock is not released properly. This allows local...
