CVE-2026-93158: crypto: sa2ul - stop probe if context pool creation fails

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 04c46784ec249cac995e31f0691397b82bdaa5fd, 304dcd26bfc3ce6771c2bd3b7c0299dcfd5f4e06, 91ded4742fcde6ad415c4d8a20e5ea0dcdf4f73e.

Low priority for now. Upgrade to Linux Linux 04c46784ec249cac995e31f0691397b82bdaa5fd, 304dcd26bfc3ce6771c2bd3b7c0299dcfd5f4e06, 91ded4742fcde6ad415c4d8a20e5ea0dcdf4f73e or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
