Doc Text:
A vulnerability was found in the Linux Kernel's memory management subsystem, where a race condition while attempting to remove dquot information from the rb tree can lead to a kernel panic. The race condition occurs due to a lack of proper protections when fetching the rb_tree root node. Given the right timing, this could cause the shmem_relewase_dquot() function to trigger a panic because it cannot find a node in the tree, when the reason is that the root node was changed before the search starts. This issue can lead to system instability.
