Solve this problem by adding checks to platform data. • https://git.kernel.org/stable/c/dc245a5f9b5163511e0c164c8aa47848f07b75a9 https://git.kernel.org/stable/c/ced1c04e82e3ecc246b921b9733f0df0866aa50d https://git.kernel.org/stable/c/5a53f97cd5977911850b695add057f9965c1a2d6 https://git.kernel.org/stable/c/b6208d1567f929105011bcdfd738f59a6bdc1088 https://git.kernel.org/stable/c/dc03866b5f4aa2668946f8384a1e5286ae53bbaa https://git.kernel.org/stable/c/a2ed3b780f34e4a6403064208bc2c99d1ed85026 https://git.kernel.org/stable/c/901070571bc191d1d8d7a1379bc5ba9446200999 https://git.kernel.org/stable/c/4a058b34b52ed3feb1f3ff6fd26aefeee •

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-56571 – media: uvcvideo: Require entities to have a non-zero unique ID
https://notcve.org/view.php?id=CVE-2024-56571
In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Require entities to have a non-zero unique ID Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero unique ID. ``` Each Unit and Terminal within the video function is assigned a unique identification number, the Unit ID (UID) or Terminal ID (TID), contained in the bUnitID or bTerminalID field of the descriptor. The value 0x00 is reserved for undefined ID, ``` So, deny allocating an entity with ID 0 or an ID that belongs to a unit that is already added to the list of entities. This also prevents some syzkaller reproducers from triggering warnings due to a chain of entities referring to themselves. In one particular case, an Output Unit is connected to an Input Unit, both with the same ID of 1. But when looking up for the source ID of the Output Unit, that same entity is found instead of the input entity, which leads to such warnings. In another case, a backward chain was considered finished as the source ID was 0. Later on, that entity was found, but its pads were not valid. Here is a sample stack trace for one of those cases.

In the Linux kernel, the following vulnerability has been resolved: ovl: Filter invalid inodes with missing lookup function Add a check to the ovl_dentry_weird() function to prevent the processing of directory inodes that lack the lookup function. This is important because such inodes can cause errors in overlayfs when passed to the lowerstack. • https://git.kernel.org/stable/c/f9248e2f73fb4afe08324485e98c815ac084d166 https://git.kernel.org/stable/c/5f86e79c0b2287ffdabe6c1b305a36c4e0f40fe3 https://git.kernel.org/stable/c/749eac5a6687ec99116e0691d0d71225254654e3 https://git.kernel.org/stable/c/ff43d008bbf9b27ada434d6455f039a5ef6cee53 https://git.kernel.org/stable/c/065bf5dd21639f80e68450de16bda829784dbb8c https://git.kernel.org/stable/c/72014e7745cc8250bb8f27bd78694dfd3f1b5773 https://git.kernel.org/stable/c/c8b359dddb418c60df1a69beea01d1b3322bfe83 •

In the Linux kernel, the following vulnerability has been resolved: ftrace: Fix regression with module command in stack_trace_filter When executing the following command: # echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter The current mod command causes a null pointer dereference. While commit 0f17976568b3f ("ftrace: Fix regression with module command in stack_trace_filter") has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash. • https://git.kernel.org/stable/c/04ec7bb642b77374b53731b795b5654b5aff1c00 https://git.kernel.org/stable/c/43ca32ce12888fb0eeb2d74dfc558dea60d3473e https://git.kernel.org/stable/c/5dabb7af57bc72308a6e2e81a5dd756eef283803 https://git.kernel.org/stable/c/885109aa0c70639527dd6a65c82e63c9ac055e3d https://git.kernel.org/stable/c/7ae27880de3482e063fcc1f72d9a298d0d391407 https://git.kernel.org/stable/c/8a92dc4df89c50bdb26667419ea70e0abbce456e https://git.kernel.org/stable/c/19cacabdd5a8487ae566cbecb4d03bcb038a067e https://git.kernel.org/stable/c/45af52e7d3b8560f21d139b3759735eea •
