CVE-2023-3138 – libX11: InitExt.c can overwrite unintended portions of the Display structure if the extension request leads to a buffer overflow
https://notcve.org/view.php?id=CVE-2023-3138
A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver adhering to the bounds specified in the X11 protocol, as all X servers provided by X.Org do. As the protocol only specifies a single byte for these values, an out-of-bounds value provided by a malicious server (or a malicious proxy-in-the-middle) can only overwrite other portions of the Display structure and not write outside the bounds of the Display structure itself, possibly causing the client to crash with this memory corruption. • https://access.redhat.com/security/cve/CVE-2023-3138 https://gitlab.freedesktop.org/xorg/lib/libx11/-/commit/304a654a0d57bf0f00d8998185f0360332cfa36c https://lists.x.org/archives/xorg-announce/2023-June/003406.html https://lists.x.org/archives/xorg-announce/2023-June/003407.html https://security.netapp.com/advisory/ntap-20231208-0008 https://bugzilla.redhat.com/show_bug.cgi?id=2213748 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2023-3161 – kernel: fbcon: shift-out-of-bounds in fbcon_set_font()
https://notcve.org/view.php?id=CVE-2023-3161
A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds occurs leading to undefined behavior and possible denial of service.

CVE-2023-3027 – ACM: governance policy propagator privilege escalation
https://notcve.org/view.php?id=CVE-2023-3027
The grc-policy-propagator allows security escalation within the cluster. The propagator allows policies which contain some dynamically obtained values (instead of the policy apply a static manifest on a managed cluster) of taking advantage of cluster scoped access in a created policy. This feature does not restrict properly to lookup content from the namespace where the policy was created. • https://bugzilla.redhat.com/show_bug.cgi?id=2211468#c0 https://access.redhat.com/security/cve/CVE-2023-3027 https://bugzilla.redhat.com/show_bug.cgi?id=2211468 • CWE-269: Improper Privilege Management •
