https://notcve.org/view.php?id=CVE-2024-46744
In the Linux kernel, the following vulnerability has been resolved: Squashfs: sanity check symbolic link size Syzkiller reports a "KMSAN: uninit-value in pick_link" bug. This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk. The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events: 1. squashfs_read_inode() is called to read the symbolic link from disk. • https://git.kernel.org/stable/c/f82cb7f24032ed023fc67d26ea9bf322d8431a90 https://git.kernel.org/stable/c/1b9451ba6f21478a75288ea3e3fca4be35e2a438 https://git.kernel.org/stable/c/5c8906de98d0d7ad42ff3edf2cb6cd7e0ea658c4 https://git.kernel.org/stable/c/087f25b2d36adae19951114ffcbb7106ed405ebb https://git.kernel.org/stable/c/fac5e82ab1334fc8ed6ff7183702df634bd1d93d https://git.kernel.org/stable/c/c3af7e460a526007e4bed1ce3623274a1a6afe5e https://git.kernel.org/stable/c/ef4e249971eb77ec33d74c5c3de1e2576faf6c90 https://git.kernel.org/stable/c/810ee43d9cd245d138a2733d87a24858a •
