CVSS: 6.5EPSS: 0%CPEs: 277EXPL: 1CVE-2023-4969 – GPU kernel implementations susceptible to memory leak
https://notcve.org/view.php?id=CVE-2023-4969
16 Jan 2024 — A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures. Un kernel de GPU puede leer datos confidenciales de otro kernel de GPU (incluso de otro usuario o aplicación) a través de una región de memoria de GPU optimizada llamada _local memory_ en varias arquitecturas. • https://blog.trailofbits.com • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2023-20593
24 Jul 2023 — An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. A flaw was found in hw, in “Zen 2” CPUs. This issue may allow an attacker to access sensitive information under specific microarchitectural circumstances. Daniel Moghimi discovered that some Intel Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensiti... • https://github.com/sbaresearch/stop-zenbleed-win • CWE-209: Generation of Error Message Containing Sensitive Information CWE-1239: Improper Zeroization of Hardware Register •
