Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.75.4

medium Tenable Self-Hosted Container Security Plugin ID 466901

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: ext4: fix i_data_sem unlock order in
 ext4_ind_migrate() Fuzzing reports a possible deadlock in jbd2_log_wait_commit. This issue is triggered
 when an EXT4_IOC_MIGRATE ioctl is set to require synchronous updates because the file descriptor is opened
 with O_SYNC. This can lead to the jbd2_journal_stop() function calling jbd2_might_wait_for_commit(),
 potentially causing a deadlock if the EXT4_IOC_MIGRATE call races with a write(2) system call. This
 problem only arises when CONFIG_PROVE_LOCKING is enabled. In this case, the jbd2_might_wait_for_commit
 macro locks jbd2_handle in the jbd2_journal_stop function while i_data_sem is locked. This triggers
 lockdep because the jbd2_journal_start function might also lock the same jbd2_handle simultaneously. Found
 by Linux Verification Center (linuxtesting.org) with syzkaller. Rule: add (CVE-2024-50006)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.75.4 or later.
