**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A NULL pointer dereference error in the Linux kernel has been resolved. The issue occurred in the `btbcm get board name()` function, where `devm kstrdup()` can return a NULL pointer on failure, but this returned value was not checked. This could lead to a kernel NULL pointer dereference error. **Recommendations** For the affected Linux kernel versions, add a NULL check in the `btbcm get board name()` function to handle the kernel NULL pointer dereference error. 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** A issue has been identified in the Linux kernel related to the mt7925 wifi driver. Specifically, in the `mt7925 change vif links()` function, `devm kzalloc()` may return NULL, but this returned value is not checked, potentially leading to a NULL dereference. **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** A potential null dereference issue has been identified in the firewire kunit test of the Linux kernel. The `kunit kzalloc()` function may return a NULL pointer, and without a proper NULL check, dereferencing it could lead to a null dereference. This issue is resolved by adding a NULL check for `test state`. **Recommendations** For the affected Linux kernel version, add a NULL check for `test state` to prevent potential null dereference.

**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.6.74 **Description** A vulnerability in the Linux kernel has been resolved. The issue is related to the gpio: grgpio component, where the function `grgpio probe` does not check for a NULL pointer returned by `devm kasprintf()` in case of an error. This can lead to a kernel NULL pointer dereference error. **Recommendations** For Linux kernel versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider adding a NULL check in `grgpio probe` to handle the kernel NULL pointer dereference error until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A NULL dereference issue has been resolved in the Linux kernel. The problem occurs in the `rtk usb3phy probe()` function, where `devm kzalloc()` may return `NULL`, but this returned value is not checked. This issue is related to the Realtek USB phy driver. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
