In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: stmmac: initialize ptp_lock at probe time<\/p>\n
priv->ptp_lock is only initialized in stmmac_ptp_register(), which runs
\nduring __stmmac_open(). However, the lock is also used while the
\ninterface is down and has never been opened: tc_taprio_configure()
\ninvokes the PTP gettime64() callback to compute the EST base time when
\noffloading a TAPRIO schedule, and stmmac_get_time() takes
\npriv->ptp_lock. Using an uninitialized rwlock is undefined behaviour.
\nMove the rwlock_init() to __stmmac_dvr_probe(), together with the other
\nprivate locks, so that ptp_lock is always valid regardless of the
\ninterface state.<\/p>\n","protected":false},"excerpt":{"rendered":"
