Red Hat Security Advisory 2024-3855-03 - An update for kernel is now available for Red Hat Enterprise Linux 9.2 Extended Update Support. Issues addressed include double free and use-after-free vulnerabilities.
Red Hat Security Advisory 2024-3854-03 - An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Extended Update Support. Issues addressed include double free and use-after-free vulnerabilities.
Ubuntu Security Notice 6821-2 - It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.
