Description OSIDB Bzimport 2025-12-24 11:03:44 UTC

In the Linux kernel, the following vulnerability has been resolved:

crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id

Use check_add_overflow() to guard against potential integer overflows
when adding the binary blob lengths and the size of an asymmetric_key_id
structure and return ERR_PTR(-EOVERFLOW) accordingly. This prevents a
possible buffer overflow when copying data from potentially malicious
X.509 certificate fields that can be arbitrarily large, such as ASN.1
INTEGER serial numbers, issuer names, etc.
