What is CVE-2022-23001?
CVE-2022-23001 is a medium-severity vulnerability in Western Digital Sweet B Library, published on 29 Jul 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
When compressing or decompressing elliptic curve points using the Sweet B library, an incorrect choice of sign bit is used. An attacker with user level privileges and no other user's assistance can exploit this vulnerability with only knowledge of the public key and the library. The resulting output may cause an error when used in other operations; for instance, verification of a valid signature under a decompressed public key may fail. This may be leveraged by an attacker to cause an error scenario in applications which use the library, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.
Weakness: CWE-682
