| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.74
Description
A race condition was found in the Linux kernel's ila add mapping() function, which could lead to a slab-use-after-free error. This issue was discovered by syzbot and is related to concurrent ILA CMD ADD commands. To fix this, a mutex was added to ensure that only one thread can call nf register net hooks() at a time. The vulnerability is related to the
nf register net hooks() function and the ila add mapping() function.Recommendations
To resolve this issue, update the Linux kernel to version 6.6.74 or later. As a temporary workaround, consider disabling the
ila add mapping() function until a patch is available. Restrict access to the vulnerable nf register net hooks() function to minimize the risk of exploitation. Avoid using the ILA CMD ADD command in the affected API endpoint until the issue is resolved.Exploit
