CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2021-4028 – kernel: use-after-free in RDMA listen()
https://notcve.org/view.php?id=CVE-2021-4028
A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system. Un fallo en la implementación del kernel de Linux del código de escucha del administrador de comunicaciones RDMA permitía a un atacante con acceso local configurar un socket para que escuchara en un puerto alto, lo que permitía un uso de memoria previamente liberada de un elemento de la lista. Dada la capacidad de ejecutar código, un atacante local podría aprovechar este uso de memoria previamente liberada para bloquear el sistema o posiblemente escalar privilegios en el sistema. A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. • https://access.redhat.com/security/cve/CVE-2021-4028 https://bugzilla.redhat.com/show_bug.cgi?id=2027201 https://bugzilla.suse.com/show_bug.cgi?id=1193167#c0 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bc0bdc5afaa74 https://lkml.org/lkml/2021/10/4/697 https://security.netapp.com/advisory/ntap-20221228-0002 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 56EXPL: 33CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. • https://github.com/dzonerzy/poc-cve-2021-4034 https://github.com/arthepsy/CVE-2021-4034 https://github.com/berdav/CVE-2021-4034 https://www.exploit-db.com/exploits/50689 https://github.com/PwnFunction/CVE-2021-4034 https://github.com/joeammond/CVE-2021-4034 https://github.com/nikaiw/CVE-2021-4034 https://github.com/ryaagard/CVE-2021-4034 https://github.com/Rvn0xsy/CVE-2021-4034 https://github.com/Ayrx/CVE-2021-4034 https://github.com/zhzyker/CVE-2021-4034& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
