**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.5.9 **Description** The issue is related to a NULL pointer dereference in the `send acknowledge` function in `net/nfc/nci/spi.c`. This could potentially allow an attacker to cause a denial of service. **Recommendations** For Linux kernel versions prior to 6.5.9, update to version 6.5.9 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A possible NULL pointer dereference in the `send acknowledge()` function has been resolved. The issue occurred due to memory allocation failure from `nci skb alloc()` (which calls `alloc skb()`). This resolution aims to avoid the possible NULL pointer dereference by handling the memory allocation failure. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
