CVE-2026-80871

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The xilinx-trng driver contains issues within the crypto rng interface. The function xtrng trng generate() may incorrectly return a success status even when it fails to fill all requested bytes in the buffer. Additionally, a concurrency issue exists where xtrng trng generate() and xtrng hwrng trng read() can run simultaneously and interfere with each other due to broken locking code in the xtrng hwrng trng read() function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
