CVE-2026-80922

CVE-2026-80922 affects the Linux kernel component crypto: qcom-rng (Qualcomm RNG driver). The root cause is that the driver incorrectly rejected zero as an invalid random number, even though zero is a legitimate random value. This rejection makes the RNG output distinguishable from true randomnes...

CVE-2026-80921

CVE-2026-80921 affects the Linux kernel in the KVM s390 vsie (Virtual SIE) subsystem. When shadowing crypto access bits from a format0 apcb (crycb 0 or 1), bits 64–255 retain stale values from the vsie page, potentially allowing a nested guest to access a device no longer available . The CVSS 3.1...
