Since the structure is stored in shared\nAMDXDNA_BO_SHARE memory, userspace can modify command_count concurrently.\nIf command_count is changed to zero, the bounds check generated from\n__counted_by may fail and trigger a kernel panic.\n\nRemove __counted_by to avoid relying on the userspace-controlled\ncommand_count for the flexible array bounds check.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/52f3e086760a9a3e02a46a10b57caffd73b1c204","tags":[]},{"url":"https://git.kernel.org/stable/c/93fa3e925b15b0ded0a549fe7f12bfbb1c4e171a","tags":[]},{"url":"https://git.kernel.org/stable/c/b3709d354545e70388177500761f92d906c4dfd6","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
