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...

SUSE CVE-2026-45536

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, nettyunixsocketrecvFd sets msgcontrol to char controlCMSGSPACEsizeofint line 940 - 24 bytes on 64-bit Linux. A peer-sent SCMRIGHTS cmsg carrying two ints has...

CVE-2026-45536 Netty: Unix-socket fd receive leaks descriptors when peer sends two at once

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...

Name of the Vulnerable Software and Affected Versions Netty affected versions not specified Description A file descriptor leak occurs in the netty unix socket recvFd function when a peer sends two file descriptors simultaneously via an SCM RIGHTS control message. The system allocates a control...

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...

Name of the Vulnerable Software and Affected Versions Linux kernel versions 6.4 through 6.12.67 Description A race condition in the epoll subsystem leads to a use-after-free UAF scenario. The ep remove function via ep remove file clears file-f ep under file-f lock but continues to use the @file...

CVE-2026-46015

A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...
