Subject: [GIT PULL] probes: Fixes for v6.12-rc4


Hi Linus,

Probes fixes for v6.12-rc4:

- uprobe: avoid out-of-bounds memory access of fetching args
  Uprobe trace events can cause out-of-bounds memory access when fetching
  user-space data which is bigger than one page, because it does not check
  the local CPU buffer size when reading the data. This checks the read
  data size and cut it down to the local CPU buffer size.
