This may leak the kernel\nstack contents. Make gpio_desc_to_lineinfo() return int so that the\n-ENODEV returned on failure to acquire the guard can be propagated to\nthe callers.\n\nWhile not strictly necessary: move the memset() before trying to acquire\nthe SRCU read lock too for good measure.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1feb5d39b05afd902ed9fc902ec5b15be03a4bdb","tags":[]},{"url":"https://git.kernel.org/stable/c/60a466f231905cd96ae6f0f3c44a710c97873dac","tags":[]},{"url":"https://git.kernel.org/stable/c/8460ee5216ab9a38263b01dca4b0a27e083f70f3","tags":[]},{"url":"https://git.kernel.org/stable/c/cf3d043582e106a0e57002bec8a6de8929ba3e1c","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
