**Name of the Vulnerable Software and Affected Versions** NETGEAR RAX30 (affected versions not specified) **Description** This issue allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. The specific flaw exists within the UPnP service, resulting from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Authentication is not required to exploit this vulnerability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Authentication is not required to exploit this issue. The specific flaw exists within the DHCP server, resulting from the lack of proper validation of a user-supplied string before using it to execute a system call.

**Name of the Vulnerable Software and Affected Versions** TP-Link Archer AX21 (AX1800) (affected versions not specified) **Description** The issue is related to a buffer overflow vulnerability in the TP-Link AX1800 router's firmware, allowing remote attackers to execute arbitrary code on affected installations. The flaw exists within the parsing of firmware images due to the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. This can be leveraged to execute code in the context of root. Authentication is not required to exploit this vulnerability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux Kernel versions 2.6.24 through 5.16.11 Linux Kernel versions 5.15.0 through 5.15.25 Linux Kernel versions 5.10.0 through 5.10.96 Linux Kernel versions 5.4.0 through 5.4.176 Linux Kernel versions 4.19.0 through 4.19.228 Linux Kernel versions 4.14.0 through 4.14.265 Linux Kernel versions 4.9.0 through 4.9.300 **Description** An improper authentication flaw exists in the `cgroup release agent write` function within the `kernel/cgroup/cgroup-v1.c` file of the Linux kernel. This issue stems from a lack of privilege control when configuring the `release agent` feature of cgroups v1 (Control Groups v1), which are Linux functions used to limit, account for, and isolate resource use for sets of processes. Under certain circumstances, this allows an attacker to execute arbitrary commands with elevated privileges, bypass namespace isolation, and escape containerized environments to gain root-level access on the host system. This flaw has been actively exploited in real-world attacks. **Recommendations** Update the kernel to versions 5.16.12, 5.15.26, 5.10.97, 5.4.177, 4.19.229, 4.14.266, or 4.9.301 depending on the current release branch. Enable AppArmor or SELinux. Enable Seccomp.
