CVE-2025-62491
A Use-After-Free UAF vulnerability exists in the QuickJS engine's standard library when iterating over the global list of unhandled rejected promises ts-rejectedpromiselist. The function jsstdpromiserejectioncheck attempts to iterate over the rejectedpromiselist to report unhandled rejections usi...
CVE-2025-62490
In quickjs, in jsprintobject, when printing an array, the function first fetches the array length and then loops over it. The issue is, printing a value is not side-effect free. An attacker-defined callback could run during jsprintvalue, during which the array could get resized and len1 become ou...
CVE-2025-62492
A vulnerability stemming from floating-point arithmetic precision errors exists in the QuickJS engine's implementation of TypedArray.prototype.indexOf when a negative fromIndex argument is supplied. The fromIndex argument read as a double variable, $d$ is used to calculate the starting position f...

DEBIAN-CVE-2025-62493
A vulnerability exists in the QuickJS engine's BigInt string conversion logic jsbiginttostring1 due to an incorrect calculation of the required number of digits, which in turn leads to reading memory past the allocated BigInt structure. The function determines the number of characters ndigits...

UBUNTU-CVE-2025-62494
A type confusion vulnerability exists in the handling of the string addition + operation within the QuickJS engine. The code first checks if the left-hand operand is a string. It then attempts to convert the right-hand operand to a primitive value using JSToPrimitiveFree. This conversion can...
UBUNTU-CVE-2025-62496
A vulnerability exists in the QuickJS engine's BigInt string parsing logic jsbigintfromstring when attempting to create a BigInt from a string with an excessively large number of digits. The function calculates the necessary number of bits nbits required to store the BigInt using the formula:...
UBUNTU-CVE-2025-62495
An integer overflow vulnerability exists in the QuickJS regular expression engine libregexp due to an inconsistent representation of the bytecode buffer size. The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\textsize\textt$ an unsigned type, typically...

CVE-2025-62496
The CVE refers to QuickJS: BigInt parsing in js_bigint_from_string. When converting a decimal string with an extremely large number of digits, the code computes n_bits as (n_digits × 27 + 7) / 8. For very large inputs (e.g., tens of millions of digits), this intermediate value overflows a 32-bit ...
