CVE-2026-57019 affects Junos OS on MX Series. An issue in the Packet Forwarding Engine (pfe) due to improper validation of a specified quantity in input can allow an unauthenticated adjacent attacker to cause a Denial-of-Service by triggering an FPC major error and a reset, impacting traffic unti...

The vulnerability of the mpls_do_error() function in the sys/netmpls/mpls_input.c script of the OpenBSD operating system, which allows a hacker to disclose protected information

The vulnerability of the mplsdoerror function in the sys/netmpls/mplsinput.c file of the OpenBSD operating system is related to the issue of operations going out of the buffer boundaries during the processing of MPLS tags. Exploitation of this vulnerability can allow a remote attacker to disclose...

CVE-2026-56099

OpenBSD before commit 6a23123 (2026-06-18) contains an out-of-bounds read in sys/netmpls/mpls_input.c:mpls_do_error, allowing remote disclosure of kernel stack memory by crafting MPLS frames with 16 labels and no Bottom-of-Stack bit. Affected component is the MPLS input handling path; root cause ...
