- CWE-121 - Stack-based Buffer Overflow
Summary
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.

Summary
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.

- CWE-1220 - Insufficient Granularity of Access Control
Summary
A privilege escalation from host to domain vulnerability was found in the FreeIPA project. The FreeIPA package fails to validate the uniqueness of the `krbCanonicalName` for the admin account by default, allowing users to create services with the same canonical name as the REALM admin. When a successful attack happens, the user can retrieve a Kerberos ticket in the name of this service, containing the admin@REALM credential. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.

Summary
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel.

- CWE-787 - Out-of-bounds Write
Summary
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.

CWE
- CWE-20 - Improper Input Validation
Summary
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.
