Can contemporary scholars authenticate or deem weak hadiths, knowing that the hadiths in Sahih al-Bukhari and Sahih Muslim are considered authentic?

The meaning of "Sahih al-Albani" is unclear. If what is meant is "Sahih al-Jami' al-Saghir," it contains 8202 hadiths, categorized as either sound (sahih) or good (hasan). He has other books, such as "Sahih al-Targhib," "Al-Adab al-Mufrad," and the four Sunan books, which contain thousands of hadiths. He also has "Al-Silsilah al-Sahihah," which contains over 4000 hadiths, most of which, along with those in "Sahih al-Jami'," are not found in the two Sahih collections (Bukhari and Muslim). Judging a hadith depends on researching its chain of narration (sanad) and text (matn). The Sheikh (al-Albani) was not unique in authenticating hadiths; rather, he relied on the statements of previous scholars. As for the hadiths in Bukhari and Muslim, their authenticity is definitively established. The Sunan books, however, include both sound and weak hadiths because their compilers did not stipulate authenticity as a condition.
