https://notcve.org/view.php?id=CVE-2024-50302
In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report. • https://git.kernel.org/stable/c/27ce405039bfe6d3f4143415c638f56a3df77dca https://git.kernel.org/stable/c/b2b6cadad699d44a8a5b2a60f3d960e00d6fb3b7 https://git.kernel.org/stable/c/fe6c9b48ebc920ff21c10c50ab2729440c734254 https://git.kernel.org/stable/c/e7ea60184e1e88a3c9e437b3265cbb6439aa7e26 https://git.kernel.org/stable/c/3f9e88f2672c4635960570ee9741778d4135ecf5 https://git.kernel.org/stable/c/d7dc68d82ab3fcfc3f65322465da3d7031d4ab46 https://git.kernel.org/stable/c/05ade5d4337867929e7ef664e7ac8e0c734f1aaf https://git.kernel.org/stable/c/1884ab3d22536a5c14b17c78c2ce76d17 •

It can be reproduced by following these steps(more details [1]): 1. Obtain more than 32 inputs that have similar hashes, which ends with the pattern '0xxxxxxxe6'. 2. Reboot and add the keys obtained in step 1. The reproducer demonstrates how this issue happened: 1. In the search_nested_keyrings function, when it iterates through the slots in a node(below tag ascend_to_node), if the slot pointer is meta and node->back_pointer != NULL(it means a root), it will proceed to descend_to_node. • https://git.kernel.org/stable/c/b2a4df200d570b2c33a57e1ebfa5896e4bc81b69 https://git.kernel.org/stable/c/c3ce634ad953ce48c75c39bdfd8b711dd95f346f https://git.kernel.org/stable/c/4efb69a0e294ef201bcdf7ce3d6202cd0a545a5d https://git.kernel.org/stable/c/1e4332581cd4eed75aea77af6f66cdcdda8b49b9 https://git.kernel.org/stable/c/199c20fb7499c79557a075dc24e9a7dae7d9f1ce https://git.kernel.org/stable/c/bbad2d5b6c99db468d8f88b6ba6a56ed409b4881 https://git.kernel.org/stable/c/3e79ad156bedf2da0ab909a118d2cec6c9c22b79 https://git.kernel.org/stable/c/e0a317ad68e4ea48a0158187238c5407e •
