stable inclusion from stable-v5.10.122 commit 4f0a2c46f588e09b37b831f78f9015463a4b21b6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4f0a2c46f588e09b37b831f78f9015463a4b21b6 -------------------------------- commit 77e5fe8f upstream. The first validation check for EVT_TRANSACTION has two different checks tied together with logical AND. One is a check for minimum packet length, and the other is for a valid aid_tag. If either condition is true (fails), then an error should be triggered. The fix is to change && to ||.
