Description
The issue is related to multiple vulnerabilities in the Linux kernel, which can lead to disruption of protected information. These vulnerabilities can be exploited remotely. The personality subsystem in the Linux kernel has a PER CLEAR ON SETID setting that does not clear the ADDR COMPAT LAYOUT and MMAP PAGE ZERO flags when executing a setuid or setgid program. This makes it easier for local users to conduct NULL pointer dereference attacks, bypass the mmap min addr protection mechanism, or defeat address space layout randomization (ASLR).
Recommendations
As a temporary workaround, consider disabling the
checkPassword() function until a patch is available.
Restrict access to the vulnerable module moduleX to minimize the risk of exploitation.
Avoid using the parameter user id in the affected API endpoint until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability. Found an issue in the description? Have something to add? Feel free to write us 👾
