CVE-2026-81722

nltk PorterStemmer in versions ≤ 3.10.2 is vulnerable to an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem(). The root cause is that the _is_consonant() helper walks backward over the entire run of trailing 'y' characters on every call, and _measure() invokes it for ea...

CVE-2026-59641

A flaw was found in Bouncy Castle for Java. The S/MIME Secure/Multipurpose Internet Mail Extensions validator improperly trusts the signing time asserted by the signer during path validation. This could allow an attacker to bypass certificate path validation, potentially leading to the acceptance...

Uncontrolled Resource Consumption

Bouncy Castle is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to quadratic-time processing when escaping X.500 distinguished names during stringification, which allows an attacker to supply specially crafted input that causes excessive CPU consumption and potentially...

CVE-2026-74749

A flaw was found in the Linux kernel's restartable sequences rseq mechanism. An inconsistency in the handling of lock states during time slice extensions can occur when interrupts are enabled. This can lead to a system livelock or hard lockup, effectively causing a Denial of Service DoS for the...
