CVE-2023-54288

The CVE-2023-54288 entry pertains to the Linux kernel’s wifi mac80211 stack. A deadlock risk arises in ieee80211_tx_dequeue() due to a race between spin_lock and spin_unlock around queue_stop_reason_lock when an asynchronous interrupt occurs, potentially re-locking the same spinlock. This can lea...

CVE-2023-54288

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fortify the spinlock against deadlock by interrupt In the function ieee80211txdequeue there is a particular locking sequence: begin: spinlock&local-queuestopreasonlock; qstopped = local-queuestopreasonsq;...

CVE-2023-54287

Summary of CVE-2023-54287 (Linux kernel, i.MX8MP) : The issue arises in the serial/tty imx driver when Jailhouse is enabled, potentially causing a kernel panic due to a NULL pointer dereference from a pending USR interrupt while the IRQ is not yet requested. The root cause is unsafe handling of t...

CVE-2022-50836 remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev()

In the Linux kernel, the following vulnerability has been resolved: remoteproc: sysmon: fix memory leak in qcomaddsysmonsubdev The kfree should be called when ofirqgetbyname fails or devmrequestthreadedirq fails in qcomaddsysmonsubdev, otherwise there will be a memory leak, so add kfree to fix it...

CVE-2022-50836

The CVE-2022-50836 issue in the Linux kernel’s remoteproc: sysmon subsystem (qcom_add_sysmon_subdev) caused a memory leak. Root cause: kfree() was not invoked when of_irq_get_byname() or devm_request_threaded_irq() failed, leading to leaked memory. The fix adds a kfree() path to ensure proper cle...
