CVE-2026-63824
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
KEYS: fix overflow in keyctl_pkey_params_get_2()
The length for the internal output buffer is calculated incorrectly, which
can result overflow when a too small buffer is provided.
Fix the bug by allocating internal output with the size of the maximum
length of the cryptographic primitive instead of caller provided size.
