CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42289 – scsi: qla2xxx: During vport delete send async logout explicitly
https://notcve.org/view.php?id=CVE-2024-42289
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: During vport delete send async logout explicitly During vport delete, it is observed that during unload we hit a crash because of stale entries in outstanding command array. For all these stale I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but I/Os could not complete while vport delete is in process of deleting.

https://notcve.org/view.php?id=CVE-2024-42271
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. • 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 •
