https://notcve.org/view.php?id=CVE-2023-1476
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system. Se encontró una falla de use-after-free en el código fuente de contabilidad del espacio de direcciones de memoria mm/mremap del kernel de Linux. Este problema ocurre debido a una condición de ejecución entre rmap walk y mremap, lo que permite a un usuario local bloquear el sistema o potencialmente aumentar sus privilegios en el sistema. • https://access.redhat.com/errata/RHSA-2023:1659 https://access.redhat.com/security/cve/CVE-2023-1476 https://bugzilla.redhat.com/show_bug.cgi?id=2176035 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=97113eb39fa7972722ff490b947d8af023e1f6a2 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 35EXPL: 0CVE-2023-0494 – X.Org Server DeepCopyPointerClasses Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-0494
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DeepCopyPointerClasses function. • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 https://gitlab.freedesktop.org/xorg/xserver/-/commit/0ba6d8c37071131a49790243cdac55392ecf71ec https://lists.x.org/archives/xorg-announce/2023-February/003320.html https://security.gentoo.org/glsa/202305-30 https://access.redhat.com/security/cve/CVE-2023-0494 • CWE-416: Use After Free •
