Detailed vulnerability description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to an AVX-512-optimized implementation of the mempcpy function may write data beyond the target buffer. A local attacker can trigger buffer overflow in __mempcpy_avx512_no_vzeroupper and execute arbitrary code with elevated privileges.
