 * kernel: Information leak in l2cap_parse_conf_req in net/bluetooth/l2cap_core.c (CVE-2022-42895)

 * kernel: GSM multiplexing race condition leads to privilege escalation (CVE-2023-6546,ZDI-CAN-20527)

 * kernel: ext4: kernel bug in ext4_write_inline_data_end() (CVE-2021-33631)

 * kernel: untrusted VMM can trigger int80 syscall handling (CVE-2024-25744)

 Bug Fix(es):

 * kernel: use after free flaw in l2cap_conn_del in net/bluetooth/l2cap_core.c (JIRA:RHEL-18806)

 * tx-checksumming required for accessing port in OpenShift for RHEL 8.6 (JIRA:RHEL-20821)

 * ceph: several cap and snap fixes (JIRA:RHEL-20908)

 * unable to access smsc95xx based interface unless you start outgoing traffic. (JIRA:RHEL-25718)

 * [RHEL8] ] BUG bio-696 (Not tainted): Poison overwritten (JIRA:RHEL-26100)

 * kernel: ext4: kernel bug in ext4_write_inline_data_end() (JIRA:RHEL-26330)

 * kernel: Information leak in l2cap_parse_conf_req in net/bluetooth/l2cap_core.c (JIRA:RHEL-18808)

 * kernel: GSM multiplexing race condition leads to privilege escalation (JIRA:RHEL-19953)

 Enhancement(s):

 * [IBM 8.10 FEAT] Upgrade the qeth driver to latest from upstream, e.g. kernel 6.4 (JIRA:RHEL-25810)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
