CVE-2024-47723 – jfs: fix out-of-bounds in dbNextAG() and diAlloc()
https://notcve.org/view.php?id=CVE-2024-47723
In the Linux kernel, the following vulnerability has been resolved: jfs: fix out-of-bounds in dbNextAG() and diAlloc() In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the case where agno is greater or same than MAXAG should be added in diAlloc() to prevent out-of-bounds. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/d1017d2a0f3f16dc1db5120e7ddbe7c6680425b0 https://git.kernel.org/stable/c/5ad6284c8d433f8a213111c5c44ead4d9705b622 https://git.kernel.org/stable/c/0338e66cba272351ca9d7d03f3628e390e70963b https://git.kernel.org/stable/c/ead82533278502428883085a787d5a00f15e5eb9 https://git.kernel.org/stable/c/6ce8b6ab44a8b5918c0ee373d4ad19d19017931b https://git.kernel.org/stable/c/c1ba4b8ca799ff1d99d01f37d7ccb7d5ba5533d2 https://git.kernel.org/stable/c/128d5cfdcf844cb690c9295a3a1c1114c •
CVE-2023-52917 – ntb: intel: Fix the NULL vs IS_ERR() bug for debugfs_create_dir()
https://notcve.org/view.php?id=CVE-2023-52917
In the Linux kernel, the following vulnerability has been resolved: ntb: intel: Fix the NULL vs IS_ERR() bug for debugfs_create_dir() The debugfs_create_dir() function returns error pointers. It never returns NULL. So use IS_ERR() to check it. • https://git.kernel.org/stable/c/e26a5843f7f5014ae4460030ca4de029a3ac35d3 https://git.kernel.org/stable/c/20cbc281033ef5324f67f2d54bc539968f937255 https://git.kernel.org/stable/c/4b2fbba4e44630a59b09d32627b63c4ffdf70f78 https://git.kernel.org/stable/c/ef7e34237e2612b116a84c9640628a6f7a0d693e https://git.kernel.org/stable/c/a429158f2e0a7a03eb67fd5e204e1f6735c725aa https://git.kernel.org/stable/c/7cbd6d7fb9ba2be03978809c848e2e50eaeead2c https://git.kernel.org/stable/c/16e5bed6c1883b19f9fcbdff996aa3381954d5f3 https://git.kernel.org/stable/c/b66bf833e72a1e23d7ccafc0f8f74e80f •
