**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability has been resolved in the Linux kernel where the ENETC PF and VF drivers share a function to configure MQPRIO, but only PF can configure preemptible TCs. This is because only PF has related registers, while VF does not. As a result, VF will access an invalid pointer when trying to access a non-existent register, causing a crash issue. Some PFs, such as eno1 and eno3 on LS1028A, also do not support configuring preemptible TCs and should be prevented from accessing these unimplemented registers. **Recommendations** To resolve the issue, update to a version of the Linux kernel that includes the fix, such as version 6.6.74 or later. Additionally, consider disabling the `enetc setup tc mqprio()` function for VF drivers until a patch is available. Restrict access to the `enetc change preemptible tcs()` function for PF drivers that do not support configuring preemptible TCs, such as eno1 and eno3 on LS1028A.

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.61 Description: The issue is related to a crash in the SPI driver when not using GPIO chip select. The problem occurs because a NULL pointer is passed to `gpiod direction output()` when `spi get csgpiod()` returns a NULL value. This can cause a kernel NULL pointer dereference, leading to a crash. The crash is accompanied by an error message indicating a level 0 translation fault. Recommendations: To resolve the issue, update the Linux kernel to version 6.6.61 or later. As a temporary workaround, consider disabling the SPI driver or avoiding the use of GPIO chip select until a patch is available.

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.15.5 Description: The vulnerability is related to the xhci-plat component in the Linux kernel, which is responsible for handling USB connections. The issue arises when the system is suspended and remote wake is enabled, causing a crash due to a synchronous external abort. This problem was hidden by the power domain driver, which called runtime resume before suspend, but a commit removed this call, making the issue happen. The vulnerability can be exploited by an attacker to cause a denial of service. Recommendations: To resolve the issue, update the Linux kernel to a version that includes the fix for the vulnerability, specifically the patch that calls runtime resume before suspend to ensure the clock is on before accessing the register. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to a use-after-free vulnerability in the `cdns3 gadget ep disable()` function. This vulnerability can be exploited to impact the confidentiality and availability of protected information. The problem occurs because `list del init()` uses `priv req->list` after it has been freed at `cdns3 gadget ep free request()`. To resolve this issue, `list del init()` should be moved before `cdns3 gadget ep free request()`. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to a memory double free vulnerability in the Linux kernel's USB Cadence driver. When handling a zero packet, the driver appends an additional zero packet request, which leads to a double free condition. This occurs because the `usb gadget giveback request()` function frees the request, and then the `cdns3 gadget ep free request()` function also attempts to free the same request again. The vulnerability can potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the fsl-qdma component of the Linux kernel, where unaligned read transactions initiated by QDMA may stall in the Network On-Chip (NOC), causing a deadlock condition. This can lead to completion timeouts in the PCIe controller. The problem is associated with chip errata, specifically the ls1028a chip. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited. **Recommendations** To resolve the issue, enable prefetch by setting the source descriptor prefetchable bit (SD[PF] = 1) as a workaround. Implement this workaround to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 68.0.3440.75 **Description** The issue is related to an information leak in the media engine of Google Chrome, which can be exploited by a remote attacker using a crafted HTML page. This allows the attacker to obtain potentially sensitive information from process memory. The vulnerability is also related to the Blink web page display mechanism and involves bypassing the Cross-origin resource sharing (CORS) mechanism, potentially allowing unauthorized access to protected information. **Recommendations** For Google Chrome versions prior to 68.0.3440.75, update to version 68.0.3440.75 or later to resolve the issue. As a temporary workaround, consider avoiding the use of crafted HTML pages that could exploit the vulnerability in the media engine. Restrict access to sensitive information to minimize the risk of exploitation until the update is applied.
