In the Linux kernel, the following vulnerability has been resolved: xfrm: The issue occurs in the error path of the xfrmpolicycheck function. When the fetching process of the object pols1 fails, the function simply returns 0, without decrementing the reference count of pols0. This happens either...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The reference count leak in smbcheckpermdacl has been fixed. The issue occurs in a specific part of smbcheckpermdacl. When “id” and “uid” have the same value, the function simply jumps out of the loop without decrementing...

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fixed the issue of double module refcount decrementation. Once the discipline is associated with the device, deleting the device will cause the module’s refcount to be decreased. Performing this operation manually alon...

Astra Linux – Vulnerability in krb5

In MIT Kerberos 5 also known as krb5, before version 1.21.3, an attacker could modify the plaintext Extra Count field of a confidential GSS krb5 wrap token. This modification caused the unwrapped token to appear truncated, affecting the application...
