(CVE-2023-6915)\n\nRobert Morris discovered that the CIFS network file system implementation\nin the Linux kernel did not properly validate certain server commands\nfields, leading to an out-of-bounds read vulnerability. An attacker could\nuse this to cause a denial of service (system crash) or possibly expose\nsensitive information. (CVE-2024-0565)\n\nJann Horn discovered that the TLS subsystem in the Linux kernel did not\nproperly handle spliced messages, leading to an out-of-bounds write\nvulnerability.
