In bindervmaclose of binder.c, there is a potential exploit after the free function call due to improper locking. This could lead to a local escalation of privileges without the need for additional execution privileges. User interaction is not required for this exploitation. Product: Android...

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 SMB2LOGOFF and SMB2CLOSE commands. The issue arises from the lack of proper locking when performing operations on an object. An attacker can...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: “interconnect”: Do not access reqlist while it is being manipulated. The icclock mutex was split into separate icclock and iccbwlock mutexes in 1 to avoid lockdep splats. However, this did not adequately protect access to...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: nfc: nci: fixed a circular locking dependency in nciclosedevice. The nciclosedevice function flushes the rxwq and txwq queues while holding the reqlock. This causes a circular locking dependency, as the ncirxwork function...

In ipcheckmcrcu of igmp.c, there is a potential use after free due to improper locking. This could lead to a local escalation of privileges when opening and closing inet sockets, without the need for additional execution privileges. User interaction is not required for exploitation. Product:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: fixed the issue of locking in the ieee80211startap error path. We need to hold the local-mtx to release the channel context; this is even encoded in the lockdepassertheld function. Fix this issue...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: nvmet-tcp: fixed incorrect locking in the statechange sk callback We are not changing anything in the TCP connection state, so we should not use a writelock but rather a read lock. This caused a deadlock when running nvmet-tcp...
