DESCRIPTION
* CVE-2022-45886: Use-after-free in DVB Core driver.
A race condition in the network component of the DVB Core driver can
lead to a use-after-free when a device is disconnected. A local user
can exploit this flaw to cause a denial-of-service or potentially
escalate their privileges.
* CVE-2022-45919: Use-after-free in DVB EN50221 driver.
A race condition in the network compoenent of the DVB EN50221 driver can
lead to a use-after-free when the device is disconnected. A local user

escalate their privileges.
* CVE-2023-2163: Out-of-bounds memory access in BPF program verifier.
A flaw in the BPF verifier may allow a BPF program path to be
prematurely marked as safe, potentially leading to an out-of-bounds
read or write access. An attacker could use this flaw for
denial-of-service or arbitrary code execution.
* CVE-2023-3812: Privilege escalation in TUN/TAP device driver.
A missing check on user input in TUN/TAP device driver could lead to an
out-of-bounds access. A local attacker could use this flaw to escalate
privileges.
* CVE-2023-5178: Privilege escalation in NVMe over Fabrics TCP.
A logic error when using NVMe over Fabrics TCP could lead to a
use-after-free. A remote attacker could use this flaw to escalate
privileges.
* Note: Oracle will not provide a zero-downtime update for CVE-2023-1192.
CVE-2023-1192 is a race condition which could leads to a use-after-free
in CIFS driver. A local attacker could use this flaw to cause a denial-
of-service. Oracle recommends rebooting affected machines.
* Note: Oracle will not provide a zero-downtime update for CVE-2022-45884.
A logic error when using Digital TV driver could lead to a
use-after-free or a memory leak. A local attacker could use this flaw to
cause a denial-of-service.
Oracle has determined that creating a zero-downtime update would not be
safe and recommends a reboot if such mitigation is required.
