Its\narp_dev field may contain IFNAMSIZ bytes without a NUL terminator.\n\nSuch input is passed to dev_get_by_name_rcu() or __dev_get_by_name(), where\nstrcmp() can read past the end of the stack object when a matching\nalternative interface name exists.\n\nTerminate the field before the lookup to prevent the out-of-bounds read.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1b08c5c3ac27c9ff91c5309f4a32b4e91ce2263b","tags":[]},{"url":"https://git.kernel.org/stable/c/35e716a70733472ede300540082d64c33bf3b4c9","tags":[]},{"url":"https://git.kernel.org/stable/c/414bbad9928598904313299ac9e037a73f520be1","tags":[]},{"url":"https://git.kernel.org/stable/c/47107491b48ceef0a2faa7a010cfa961f211ef9f","tags":[]},{"url":"https://git.kernel.org/stable/c/7389757d88f54237951d7497d9c4dae7cc6d64be","tags":[]},{"url":"https://git.kernel.org/stable/c/ae6d704dbf9542b0a0830ec91a2db4f30307e7d8","tags":[]},{"url":"https://git.kernel.org/stable/c/ba664d83638640cf454b65167339cbf20dfd6f10","tags":[]},{"url":"https://git.kernel.org/stable/c/d8b6529e80bcb4fb8177121404cbb3377acaebd2","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
