https://notcve.org/view.php?id=CVE-2024-50238
In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usbc: fix NULL-deref on runtime suspend Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation") removed most users of the platform device driver data from the qcom-qmp-usb driver, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. This bug was later reproduced when the driver was copied to create the qmp-usbc driver. Restore the driver data initialisation at probe to avoid a NULL-pointer dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled manually through sysfs, with these drivers. • https://git.kernel.org/stable/c/19281571a4d5b6049dad9318db081af48818b1d2 https://git.kernel.org/stable/c/bdb35fcff34af08fc7a7cb92f99ff1442e975cb1 https://git.kernel.org/stable/c/c7086dc0539b1b2b61c8c735186698bca4858246 https://git.kernel.org/stable/c/34c21f94fa1e147a19b54b6adf0c93a623b70dd8 •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-50234 – wifi: iwlegacy: Clear stale interrupts before resuming device
https://notcve.org/view.php?id=CVE-2024-50234
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlegacy: Clear stale interrupts before resuming device iwl4965 fails upon resume from hibernation on my laptop. The reason seems to be a stale interrupt which isn't being cleared out before interrupts are enabled. We end up with a race beween the resume trying to bring things back up, and the restart work (queued form the interrupt handler) trying to bring things down. Eventually the whole thing blows up. Fix the problem by clearing out any stale interrupts before interrupts get enabled during resume.
