In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
bpf: Guard conntrack opts error writes<\/p>\n
The conntrack lookup and allocation kfuncs take an opts pointer
\ntogether with an opts__sz argument. The verifier checks only the memory
\nrange described by opts__sz, but the wrappers unconditionally write
\nopts->error whenever the internal lookup or allocation helper returns an
\nerror.<\/p>\n
For an invalid size smaller than the end of opts->error, that write can
\nland outside the verifier-checked range. Keep returning NULL for invalid
\narguments, but only report the error through opts->error when the
\nsupplied size includes the field.<\/p>\n
This preserves error reporting for the supported 12-byte and 16-byte
\nlayouts, and for other invalid sizes that still include opts->error.<\/p>\n","protected":false},"excerpt":{"rendered":"
