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

In the Linux kernel, the following vulnerabilities have been resolved: sctp: Do not free the transport used by the ASCONF during DEL-IP processing. In sctpprocessasconf, the transport used to process the ASCONF chunk is cached under asconf-transport == chunk-transport; set once in sctprcv. For an...

Astra Linux – Vulnerability in Linux

A race condition in Linux kernel SCTP sockets net/sctp/socket.c before version 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If the sctpdestroysock function is called without using the socknetsk-sctp.addrwqlock lock, an element...
