kernel: block: don't overwrite bip_vcnt in bio_integrity_copy_user()

A flaw was found in the Linux kernel's block integrity subsystem. Incorrect handling of bio integrity vector counts in the biointegritycopyuser function can lead to an out-of-bounds read during write operations. This vulnerability may allow a local attacker to cause a denial of service or...
