Title
crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id
Summary
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.
Severity

Parsing occurs before certificate trust and keyring restriction checks.\nUI:N - The attacker directly invokes the keyring interface with the crafted certificate, requiring no action by another user.\nS:U - Exploitation compromises the kernel within the same host security authority and does not inherently cross a VM, IOMMU, or other distinct security boundary.\nC:H - The undersized allocation followed by oversized memcpy operations can corrupt kernel heap objects and potentially enable kernel code execution with arbitrary memory disclosure.\nI:H - The heap out-of-bounds writes can overwrite adjacent objects, function pointers, or credentials, potentially enabling arbitrary kernel writes and control-flow hijacking.\nA:H - The overflow can immediately produce an oops or kernel panic and can be triggered repeatedly by an unprivileged local attacker."
