Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.0.66

medium Tenable Cloud Security Plugin ID 466301

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: xen: privcmd: Fix possible access to a
freed kirqfd instance Nothing prevents simultaneous ioctl calls to privcmd_irqfd_assign() and
privcmd_irqfd_deassign(). If that happens, it is possible that a kirqfd created and added to the
irqfds_list by privcmd_irqfd_assign() may get removed by another thread executing
privcmd_irqfd_deassign(), while the former is still using it after dropping the locks. This can lead to a
situation where an already freed kirqfd instance may be accessed and cause kernel oops. Use SRCU locking
to prevent the same, as is done for the KVM implementation for irqfds. (CVE-2024-46762)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.0.66 or later.
