Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
The issue is related to the Linux kernel, specifically the LoongArch architecture, where an unaligned access exception can be triggered in an irq-enabled context, such as user mode. This can cause the
do ale() function to call get user(), which may lead to a sleep, resulting in a BUG message indicating a sleeping function called from an invalid context. The estimated number of potentially affected devices is not provided. There is no information about real-world incidents where this issue was exploited.Recommendations:
To resolve the issue, update to Linux kernel version 6.6.61 or later. As a temporary workaround, consider disabling the
do ale() function until a patch is available. However, this may have unintended consequences and should be approached with caution. At the moment, there is no other information about additional mitigation measures.Exploit
