CVE-2026-93158

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

crypto: sa2ul - stop probe if context pool creation fails

sa_ul_probe() calls sa_init_mem() to create the DMA pool used for

security context buffers, but ignores its return value. If pool creation

fails, probe still continues with DMA setup, algorithm registration and

child population even though later request setup depends on that pool.

Stop probing when sa_init_mem() fails, and route that failure to the PM

cleanup path without attempting to destroy an uncreated DMA pool.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
