security/keys/keyring.c:793 This issue was also reported by syzbot. 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. However, there is an exception. If node is the root, and one of
the slots points to a shortcut, it will be treated as a keyring. 2. Whether the ptr is keyring decided by
keyring_ptr_is_keyring function. However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as
ASSOC_ARRAY_PTR_SUBTYPE_MASK. 3. When 32 keys with the similar hashes are added to the tree, the ROOT has
keys with hashes that are not similar (e.g. slot 0) and it splits NODE A without using a shortcut. When
NODE A is filled with keys that all hashes are xxe6, the keys are similar, NODE A will split with a
shortcut. Finally, it forms the tree as shown below, where slot 6 points to a shortcut. NODE A
+------>+---+ ROOT | | 0 | xxe6 +---+ | +---+ xxxx | 0 | shortcut : : xxe6 +---+ | +---+ xxe6 : : | | |
xxe6 +---+ | +---+ | 6 |---+ : : xxe6 +---+ +---+ xxe6 : : | f | xxe6 +---+ +---+ xxe6 | f | +---+ 4. As
mentioned above, If a slot(slot 6) of the root points to a shortcut, it may be mistakenly transferred to a
key*, leading to a read out-of-bounds read. To fix this issue, one should jump to descend_to_node if the
ptr is a shortcut, regardless of whether the node is root or not. [1] https://lore.kernel.org/linux-

have an appropriate closes tag.] (CVE-2024-50301)
