Date: Wed, 1 May 2024 15:06:49 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2024-27078: media: v4l2-tpg: fix some memleaks in tpg_alloc Description =========== In the Linux kernel, the following vulnerability has been resolved: media: v4l2-tpg: fix some memleaks in tpg_alloc In tpg_alloc, resources should be deallocated in each and every error-handling paths, since they are allocated in for statements. Otherwise there would be memleaks because tpg_free is called only when tpg_alloc return 0. The Linux kernel CVE team has assigned CVE-2024-27078 to this issue. Affected and fixed versions =========================== Issue introduced in 3.18 with commit 63881df94d3e and fixed in 4.19.311 with commit 0de691ff547d Issue introduced in 3.18 with commit 63881df94d3e and fixed in 5.4.273 with commit 8269ab16415f Issue introduced in 3.18 with commit 63881df94d3e and fixed in 5.10.214 with commit 94303a06e185 Issue introduced in 3.18 with commit 63881df94d3e and fixed in 5.15.153 with commit 770a57922ce3 Issue introduced in 3.18 with commit 63881df94d3e and fixed in 6.1.83 with commit 6bf5c2fade8e Issue introduced in 3.18 with commit 63881df94d3e and fixed in 6.6.23 with commit 4c86c772fef0 Issue introduced in 3.18 with commit 63881df94d3e and fixed in 6.7.11 with commit 31096da07933 Issue introduced in 3.18 with commit 63881df94d3e and fixed in 6.8.2 with commit 622b1cf38521 Issue introduced in 3.18 with commit 63881df94d3e and fixed in 6.9-rc1 with commit 8cf9c5051076 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2024-27078 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/media/common/v4l2-tpg/v4l2-tpg-core.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/0de691ff547d86dd54c24b40a81f9c925df8dd77 https://git.kernel.org/stable/c/8269ab16415f2065cd792c49b0475543936cbd79 https://git.kernel.org/stable/c/94303a06e1852a366e9671fff46d19459f88cb28 https://git.kernel.org/stable/c/770a57922ce36a8476c43f7400b6501c554ea511 https://git.kernel.org/stable/c/6bf5c2fade8ed53b2d26fa9875e5b04f36c7145d https://git.kernel.org/stable/c/4c86c772fef06f5d7a66151bac42366825db0941 https://git.kernel.org/stable/c/31096da07933598da8522c54bd007376fb152a09 https://git.kernel.org/stable/c/622b1cf38521569869c8f7b9fbe9e4f1a289add7 https://git.kernel.org/stable/c/8cf9c5051076e0eb958f4361d50d8b0c3ee6691c
