Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: List: Fixed a data race around ep-rdllist. The eppoll function first calls epeventsavailable without holding a lock and checks if ep-rdllist is empty using listemptycareful, which reads from rdllist-prev. Therefore, all access...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: eventpoll: Fixed semi-unbounded recursion. Ensured that epoll instances never form a graph with more than EPMAXNESTS+1 links. Currently, eploopcheckproc ensures that the graph is free of loops and performs some recursion depth...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Media: dvb-core: Fixed an issue where incorrect reinitializations of the ringbuffer occurred upon reopening the device. The dvbdvropen function calls dvbringbufferinit, when a new reader opens the DVR device. dvbringbufferinit th...

[SECURITY] Fedora 43 Update: python-tornado-6.5.7-1.fc43

Tornado is an open source version of the scalable, non-blocking web server and tools. The framework is distinct from most mainstream web server frameworks and certainly most Python frameworks because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle...

CVE-2026-45536

CVE-2026-45536 affects Netty, specifically Unix-domain socket fd reception in netty_unix_socket_recvFd. Prior to versions 4.1.135.Final and 4.2.15.Final, a peer-sent SCM_RIGHTS message containing two fds can cause both descriptors to leak due to a mismatch between cmsg_len checks and the actual f...

Netty: Unix-socket fd receive leaks descriptors when peer sends two at once

nettyunixsocketrecvFd sets msgcontrol to char controlCMSGSPACEsizeofint line 940 — 24 bytes on 64-bit Linux. A peer-sent SCMRIGHTS cmsg carrying two ints has cmsglen = CMSGLEN8 = 24, which fits exactly with no MSGCTRUNC, so the kernel installs both fds in the receiving process. The subsequent che...

CVE-2026-42577

Netty is an asynchronous, event-driven network application framework. From 4.2.0.Final to 4.2.13.Final , Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100...
