CVE-2026-52936

A flaw was found in the Linux kernel's jitterentropy cryptographic module. A long-held spinlock during entropy collection could cause parallel readers to stall. This issue allows a local attacker to trigger a Denial of Service DoS by causing contention for the shared lock, making the system...

CVE-2026-52936

In the Linux kernel, the following vulnerability has been resolved: crypto: jitterentropy - replace long-held spinlock with mutex jentkcapirandom serializes the shared jitterentropy state, but it currently holds a spinlock across the jentreadentropy call. That path performs expensive jitter...

CVE-2026-52936

The CVE-2026-52936 entry describes a Linux kernel fix in crypto/jitterentropy where the jent_kcapi_random() path previously held a spinlock across jent_read_entropy(), causing potential stalls during entropy generation. The vulnerability arises because this spinlock protected an expensive operati...
