CVE-2026-95520 1 Redhat 2 Enterprise Linux, Hummingbird 2026-09-29 7.1 High
A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.
CVE-2026-95519 2 Redhat, Rpm 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more 2026-09-28 7.8 High
A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account.
CVE-2026-95521 2 Redhat, Rpm 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more 2026-09-28 7.8 High
A command injection flaw was found in rpm. Installing or rebuilding a source RPM whose source or spec file basenames contain a %() macro construct causes rpm to execute an attacker-controlled shell command via popen() while relocating the source file list. This allows arbitrary command execution as the invoking (typically non-root) user, simply by installing, rebuilding, or otherwise processing an untrusted .src.rpm.
CVE-2026-100691 2 Gohugo, Redhat 2 Hugo, Hummingbird 2026-09-28 5.4 Medium
Hugo versions 0.75.0 through 0.165.x contain a stored cross-site scripting vulnerability: the syntax highlighter does not escape the `lineAnchors` option before passing it to Chroma, which writes the value verbatim into the `id` and `href` attributes of the generated line-number markup. A crafted `lineAnchors` value supplied as a Markdown code fence attribute (or passed to the `highlight` template function) results in unescaped HTML in the rendered page, allowing arbitrary JavaScript to execute in the browsers of visitors to the generated site. This affects sites that build and publish Markdown from untrusted contributors; Hugo's security model otherwise considers content trusted input. Fixed in 0.166.0, where the `lineAnchors` value is HTML-escaped before being passed to Chroma.
CVE-2026-100692 2 Gohugo, Redhat 2 Hugo, Hummingbird 2026-09-28 7.5 High
Hugo is a static site generator. In versions after v0.123.0 and before v0.166.0, Hugo's symlink confinement checks stopped at the mount root itself, so a theme or module checked into themes/ (or a vendored module) could contain a symlink at a mount root (for example themes/mytheme/assets -> /some/dir/outside). Files behind such a symlink were readable during a site build through resources.Get, resources.Match and similar functions, and could be published to public/ via static mounts, bypassing the rule that theme and module mount sources must be local paths. Modules fetched via Go modules are not affected because Go module zips cannot contain symlinks, and this is not an escalation for the main project, which may already mount absolute paths by configuration. Fixed in v0.166.0, where symlinked mount roots and symlinked directories between the mount root and the module directory are treated as non-existent for all modules. As a workaround, inspect themes/ and vendored modules for symlinks at mount roots before building, or replace symlinks with explicit mounts.
CVE-2026-88840 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-26 5.3 Medium
BusyBox TLS get_client_hello() reads past the end of the input buffer when parsing a truncated ClientHello message.
CVE-2026-88264 2 Containers, Redhat 5 Crun, Enterprise Linux, Hardened Images and 2 more 2026-09-25 5.6 Medium
A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available yet.
CVE-2026-88839 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-25 6.7 Medium
BusyBox passwd/group tokenize() references a stale endpoint pointer after trimming, causing an out-of-bounds write of heap pointers.
CVE-2026-88835 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-25 6.1 Medium
BusyBox dpkg read_package_field() steps past a NUL terminator on malformed .deb packages, causing an out-of-bounds heap read.
CVE-2026-88837 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-25 6.5 Medium
BusyBox httpd treats yescrypt ($y$) password hashes as plaintext during Basic Authentication, inverting the authentication check.
CVE-2026-88831 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-25 5.3 Medium
BusyBox httpd IP deny rules with invalid CIDR prefix lengths fail open, leaving a parsed IP with a zeroed mask so the rule matches no clients.
CVE-2026-88832 2 Busybox, Redhat 3 Busybox, Hardened Images, Hummingbird 2026-09-25 7.3 High
BusyBox romfs volume ID parsing uses unbounded strlen on attacker-controlled metadata, causing a heap buffer overflow when processing crafted filesystem images.
CVE-2026-88830 2 Busybox, Redhat 2 Busybox, Hummingbird 2026-09-23 7.5 High
A unit confusion in BusyBox TLS Montgomery reduction buffer allocation causes a pre-authentication heap buffer overflow when processing a crafted ClientKeyExchange message.
