CVE-2026-93158
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.
