USN-5757-1: Linux kernel vulnerabilities

Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2022-427...

CVE-2019-15134

RIOT through 2019.07 contains a memory leak in the TCP implementation gnrctcp, allowing an attacker to consume all memory available for network packets and thus effectively stopping all network threads from working. This is related to receive in sys/net/gnrc/transportlayer/tcp/gnrctcpeventloop.c...

CVE-2019-15134

CVE-2019-15134 affects RIOT OS (GNRC TCP) up through 2019.07. The issue is a memory leak in the TCP implementation (gnrc_tcp) triggered in _receive within sys/net/gnrc/transport_layer/tcp/gnrc_tcp_eventloop.c when an ACK is received before a SYN. This can cause unbounded memory consumption for ne...

USN-3763-1: Linux kernel vulnerability
