Bottlerocket: bottlerocket-kernel-5.15, kernel-5.15: security update to 5.15.178

high Tenable Cloud Security Plugin ID 428160

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 timer use-after-free on
failed mount Syzbot has found an ODEBUG bug in ext4_fill_super The del_timer_sync function cancels the
s_err_report timer, which reminds about filesystem errors daily. We should guarantee the timer is no
longer active before kfree(sbi). When filesystem mounting fails, the flow goes to failed_mount3, where an
error occurs when ext4_stop_mmpd is called, causing a read I/O failure. This triggers the
ext4_handle_error function that ultimately re-arms the timer, leaving the s_err_report timer active before
kfree(sbi) is called. Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd.
(CVE-2024-49960)
