Astra Linux – Vulnerability in libslirp

In ncsi.c within libslirp up to 4.3.1, there is an issue of buffer over-reading. This occurs because the program attempts to read a certain amount of header data, even when that amount exceeds the total packet length...

CVE-2026-74694

A flaw was found in the Linux kernel's NCSI Network Controller Sideband Interface component. A local attacker with CAPNETADMIN capabilities could exploit a heap out-of-bounds OOB read vulnerability. By crafting a malicious NCSI command with an oversized payload length, the attacker could cause th...
