The chipmaker’s Patch Tuesday updates for February 2021 were described in 19 advisories, including four that cover high-severity vulnerabilities.
The list of high-severity flaws includes a privilege escalation issue in the Intel Solid State Drive (SSD) Toolbox, and a denial-of-service (DoS) flaw in the XMM 7360 Cell Modem that can be exploited by an unauthenticated attacker who has network access.
In its graphics drivers, Intel patched nearly two dozen vulnerabilities, including five high-severity bugs that can be exploited by authenticated attackers — four of them allow privilege escalation and one can be exploited for DoS attacks.
