In the Linux kernel, the following vulnerability has been resolved: gve: Implement gettimex64 with -EOPNOTSUPP gve implemented a ptpclock for sole use of doauxwork at this time. ptpclockgettime() and ptpsysoffset() assume every ptpclock has implemented either gettimex64 or gettime64. Stub gettimex64 and return -EOPNOTSUPP to prevent NULL dereferencing.
