Google: sys-kernel/lakitu-kernel-6_1: security update to 18137.0.0

medium Tenable Cloud Security Plugin ID 451415

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: fs: Pass AT_GETATTR_NOSEC flag to
getattr interface function When vfs_getattr_nosec() calls a filesystem's getattr interface function then
the 'nosec' should propagate into this function so that vfs_getattr_nosec() can again be called from the
filesystem's gettattr rather than vfs_getattr(). The latter would add unnecessary security checks that the
initial vfs_getattr_nosec() call wanted to avoid. Therefore, introduce the getattr flag GETATTR_NOSEC and
allow to pass with the new getattr_flags parameter to the getattr interface function. In overlayfs and
ecryptfs use this flag to determine which one of the two functions to call. In a recent code change
introduced to IMA vfs_getattr_nosec() ended up calling vfs_getattr() in overlayfs, which in turn called
security_inode_getattr() on an exiting process that did not have current->fs set anymore, which then
caused a kernel NULL pointer dereference. With this change the call to security_inode_getattr() can be
avoided, thus avoiding the NULL pointer dereference. (CVE-2023-52779)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18137.0.0 or later.
