Name of the Vulnerable Software and Affected Versions musl libc versions prior to 1.1.24

Description The issue is related to an x87 floating-point stack adjustment imbalance in the math/i386/ directory of the musl libc library. This imbalance can lead to out-of-bounds writes not present in an application's source code. In some cases, exploitation of this issue may allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.

Recommendations For musl libc versions prior to 1.1.24, update to version 1.1.24 or later to resolve the issue. As a temporary workaround, consider restricting the use of the math/i386/ directory functions until a patch is available.
