https://notcve.org/view.php?id=CVE-2024-40941
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't read past the mfuart notifcation In case the firmware sends a notification that claims it has more data than it has, we will read past that was allocated for the notification. Remove the print of the buffer, we won't see it by default. If needed, we can see the content with tracing. This was reported by KFENCE. • https://git.kernel.org/stable/c/bdccdb854f2fb473f2ac4a6108df3cbfcedd5a87 https://git.kernel.org/stable/c/15b37c6fab9d5e40ac399fa1c725118588ed649c https://git.kernel.org/stable/c/6532f18e66b384b8d4b7e5c9caca042faaa9e8de https://git.kernel.org/stable/c/46c59a25337049a2a230ce7f7c3b9f21d0aaaad7 https://git.kernel.org/stable/c/65686118845d427df27ee83a6ddd4885596b0805 https://git.kernel.org/stable/c/a8bc8276af9aeacabb773f0c267cfcdb847c6f2d https://git.kernel.org/stable/c/a05018739a5e6b9dc112c95bd4c59904062c8940 https://git.kernel.org/stable/c/acdfa33c3cf5e1cd185cc1e0486bd0ea9 • CWE-125: Out-of-bounds Read •

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: check n_ssids before accessing the ssids In some versions of cfg80211, the ssids poinet might be a valid one even though n_ssids is 0.

CVSS: 6.1EPSS: 0%CPEs: 5EXPL: 0CVE-2024-40927 – xhci: Handle TD clearing for multiple streams case
https://notcve.org/view.php?id=CVE-2024-40927
In the Linux kernel, the following vulnerability has been resolved: xhci: Handle TD clearing for multiple streams case When multiple streams are in use, multiple TDs might be in flight when an endpoint is stopped. We need to issue a Set TR Dequeue Pointer for each, to ensure everything is reset properly and the caches cleared. Change the logic so that any N>1 TDs found active for different streams are deferred until after the first one is processed, calling xhci_invalidate_cancelled_tds() again from xhci_handle_cmd_set_deq() to queue another command until we are done with all of them. Also change the error/"should never happen" paths to ensure we at least clear any affected TDs, even if we can't issue a command to clear the hardware cache, and complain loudly with an xhci_warn() if this ever happens. This problem case dates back to commit e9df17eb1408 ("USB: xhci: Correct assumptions about number of rings per endpoint.") early on in the XHCI driver's life, when stream support was first added. It was then identified but not fixed nor made into a warning in commit 674f8438c121 ("xhci: split handling halted endpoints into two steps"), which added a FIXME comment for the problem case (without materially changing the behavior as far as I can tell, though the new logic made the problem more obvious). Then later, in commit 94f339147fc3 ("xhci: Fix failure to give back some cached cancelled URBs."), it was acknowledged again. [Mathias: commit 94f339147fc3 ("xhci: Fix failure to give back some cached cancelled URBs.") was a targeted regression fix to the previously mentioned patch. Users reported issues with usb stuck after unmounting/disconnecting UAS devices. This rolled back the TD clearing of multiple streams to its original state.] Apparently the commit author was aware of the problem (yet still chose to submit it): It was still mentioned as a FIXME, an xhci_dbg() was added to log the problem condition, and the remaining issue was mentioned in the commit description. • https://git.kernel.org/stable/c/e9df17eb1408cfafa3d1844bfc7f22c7237b31b8 https://git.kernel.org/stable/c/26460c1afa311524f588e288a4941432f0de6228 https://git.kernel.org/stable/c/633f72cb6124ecda97b641fbc119340bd88d51a9 https://git.kernel.org/stable/c/949be4ec5835e0ccb3e2a8ab0e46179cb5512518 https://git.kernel.org/stable/c/61593dc413c3655e4328a351555235bc3089486a https://git.kernel.org/stable/c/5ceac4402f5d975e5a01c806438eb4e554771577 https://access.redhat.com/security/cve/CVE-2024-40927 https://bugzilla.redhat.com/show_bug.cgi?id=2297511 • CWE-820: Missing Synchronization •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-40918 – parisc: Try to fix random segmentation faults in package builds
https://notcve.org/view.php?id=CVE-2024-40918
In the Linux kernel, the following vulnerability has been resolved: parisc: Try to fix random segmentation faults in package builds PA-RISC systems with PA8800 and PA8900 processors have had problems with random segmentation faults for many years. Systems with earlier processors are much more stable. Systems with PA8800 and PA8900 processors have a large L2 cache which needs per page flushing for decent performance when a large range is flushed. The combined cache in these systems is also more sensitive to non-equivalent aliases than the caches in earlier systems. The majority of random segmentation faults that I have looked at appear to be memory corruption in memory allocated using mmap and malloc. My first attempt at fixing the random faults didn't work. On reviewing the cache code, I realized that there were two issues which the existing code didn't handle correctly. Both relate to cache move-in. • https://git.kernel.org/stable/c/5bf196f1936bf93df31112fbdfb78c03537c07b0 https://git.kernel.org/stable/c/d66f2607d89f760cdffed88b22f309c895a2af20 https://git.kernel.org/stable/c/72d95924ee35c8cd16ef52f912483ee938a34d49 •
