CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 1CVE-2023-5717 – Out-of-bounds write in Linux kernel's Linux Kernel Performance Events (perf) component
https://notcve.org/view.php?id=CVE-2023-5717
25 Oct 2023 — A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer. We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. Se puede aprovechar una vulnerabilidad de escritura fuera de límites del montón en el... • https://github.com/uthrasri/CVE-2023-5717 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-5633
23 Oct 2023 — The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges.

13 Oct 2023 — An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers.

09 Oct 2023 — A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
