**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the `tpm buf check hmac response()` function in the Linux kernel's Trusted Platform Module (TPM) driver. It involves a null pointer dereference when `TCG TPM2 HMAC` is enabled and `tpm2 sessions init()` has not been called. This can lead to a denial of service. **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 possible null pointer dereference in the `eventfs find events()` function. This can occur when the `update events attr` function is called, which performs operations on the members of the `ei` struct when `ei` is NULL. The problem arises when `ei->is freed` is set, and the function returns NULL directly. This could potentially lead to a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
