- 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. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmcWarUbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8b3R4H/j1k6K4hYlDqiVyEaAgl u1b6cJncJShKdhE3laxDDvBv6oLrAypJbxiWv6obuBLpM1VTtjAFFQB84FoJae2w 3y7UPeVrIHDnxlSDGDW3jwSh8FYaFKgLMr1pLRKw6R1ED4ZhkbEIVJ6G1qFaMrYn FCMF7ZX1E7MW2FuUI3L+vaaKop8FLZUKyW1gRDfw+IPy/UTgUJLRohMbxixdprPe W+14GHPvf/lh2MiWzVjvzaBRRiUX8OW7nA4UvvCcHQXVmzx0GmPpPuiVHC7YyhTU 6FiVFKjMsv2jbzyREP4QYPF1n16Us0WZ0ZmGLfrSHyasr7ihj1m//YWCpFxCqzLb /Js= =VBeG -----END PGP SIGNATURE----- Merge tag 'probes-fixes-v6.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull uprobe fix from Masami Hiramatsu: - 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
