Reading the sysfs entry "large_icm" causes the kernel panic due to a garbage value returned via i2c read. That garbage value causes a buffer overflow in sprintf. [Fix] * Replace sprintf with snprintf. And also add missing lock and increase the buffer size to PAGE_SIZE. [Test Case] * Run from linux: ltp/testcases/bin/read_all -d /sys -q -r 10 [Regression Potential] no known regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-bluefield/+bug/2028309/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
