Message-ID: <2025070335-CVE-2025-38145-548b@gregkh> Date: Thu, 3 Jul 2025 10:36:02 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2025-38145: soc: aspeed: Add NULL check in aspeed_lpc_enable_snoop() From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: soc: aspeed: Add NULL check in aspeed_lpc_enable_snoop() devm_kasprintf() returns NULL when memory allocation fails. Currently, aspeed_lpc_enable_snoop() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue.

Affected files ============== The file(s) affected by this issue are: drivers/soc/aspeed/aspeed-lpc-snoop.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/2beee9cf833374550e673d428ad8b6ab37c175b3 https://git.kernel.org/stable/c/c550999f939b529d28a914d5034cc4290066aea6 https://git.kernel.org/stable/c/1fd889c145722579aa038c31cbc07cfdd4d75166 https://git.kernel.org/stable/c/d62a589eaaec6385e3e2b25cf5a28b4560ace93f https://git.kernel.org/stable/c/8312b1f776f71979bf33bda7acc05b348e8792c7 https://git.kernel.org/stable/c/f697ef117ecbf3a367dfc559a6a3589905956530 https://git.kernel.org/stable/c/45b2e8b0fdd280aba04c3cc869e9ae500c44e4b7 https://git.kernel.org/stable/c/f1706e0e1a74b095cbc60375b9b1e6205f5f4c98
