In the Linux kernel, the following vulnerability has been resolved: net/iucv: fix use after free in iucv_sock_close() iucv_sever_path() is called from process context and from bh context. iucv->path is used as indicator whether somebody else is taking care of severing the path (or it is already removed / never existed). This needs to be done with atomic compare and swap, otherwise there is a small window where iucv_sock_close() will try to work with a path that has already been severed and freed by iucv_callback_connrej() called by iucv_tasklet_fn().

Ideas for a future clean-up patch: A) Correct usage of bh_lock_sock() in tasklet context, as described in Re-enqueue, if needed. This may require adding return values to the tasklet functions and thus changes to all users of iucv. B) Change iucv tasklet into worker and use only lock_sock() in af_iucv. A possible use-after-free vulnerability was found in the Linux kernel in iucv_sock_close(). This issue may lead to a crash or memory corruption. • https://git.kernel.org/stable/c/7d316b9453523498246e9e19a659c423d4c5081e https://git.kernel.org/stable/c/84f40b46787ecb67c7ad08a5bb1376141fa10c01 https://git.kernel.org/stable/c/37652fbef9809411cea55ea5fa1a170e299efcd0 https://git.kernel.org/stable/c/c65f72eec60a34ace031426e04e9aff8e5f04895 https://git.kernel.org/stable/c/ac758e1f663fe9bc64f6b47212a2aa18697524f5 https://git.kernel.org/stable/c/8b424c9e44111c5a76f41c6b741f8d4c4179d876 https://git.kernel.org/stable/c/01437282fd3904810603f3dc98d2cac6b8b6fc84 https://git.kernel.org/stable/c/69620522c48ce8215e5eb55ffbab8cafe • CWE-416: Use After Free •

In the Linux kernel, the following vulnerability has been resolved: protect the fetch of ->fd[fd] in do_dup2() from mispredictions both callers have verified that fd is not greater than ->max_fds; however, misprediction might end up with tofree = fdt->fd[fd]; being speculatively executed. That's wrong for the same reasons why it's wrong in close_fd()/file_close_fd_locked(); the same solution applies - array_index_nospec(fd, fdt->max_fds) could differ from fd only in case of speculative execution on mispredicted path. • https://git.kernel.org/stable/c/ed42e8ff509d2a61c6642d1825032072dab79f26 https://git.kernel.org/stable/c/41a6c31df77bd8e050136b0a200b537da9e1084a https://git.kernel.org/stable/c/08775b3d6ed117cf4518754ec7300ee42b6a5368 https://git.kernel.org/stable/c/3f480493550b6a23d3a65d095d6569d4a7f56a0f https://git.kernel.org/stable/c/5db999fff545b924b24c9afd368ef5c17279b176 https://git.kernel.org/stable/c/da72e783afd27d9f487836b2e6738146c0edd149 https://git.kernel.org/stable/c/1171ceccabfd596ca370c5d2cbb47d110c3f2fe1 https://git.kernel.org/stable/c/8aa37bde1a7b645816cda8b80df4753ec • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •
