CVE-2025-38006

CVE-2025-38006 affects the Linux kernel MCTP path: in net/mctp, mctp_dump_addrinfo may read uninitialized memory from ifaddrmsg when filtering by ifa_index if the struct isaddrmsg is not provided. This can occur during certain netlink dumps (e.g., from syzkaller/busybox ip addr show). The issue i...

CVE-2025-38006 net: mctp: Don't access ifa_index when missing

In the Linux kernel, the following vulnerability has been resolved: net: mctp: Don't access ifaindex when missing In mctpdumpaddrinfo, ifaindex can be used to filter interfaces, but only when the struct ifaddrmsg is provided. Otherwise it will be comparing to uninitialised memory - reproducible i...

CVE-2025-6199 Gdk-pixbuf: uninitialized memory disclosure in gdkpixbuf gif lzw decoder

A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the...
