Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 20 for SLE 15 SP3)
Description of the patch: This update for the Linux Kernel 5.3.18-150300_59_76 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-1390: Fixed remote DoS vulnerability in tipc_link_xmit() (bsc#1210779).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Vulnerability from csaf_suse - Published: 2023-06-29 12:06 - Updated: 2023-06-29 12:06Summary
Security update for the Linux Kernel (Live Patch 2 for SLE 15 SP4)
Severity
Important
Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 2 for SLE 15 SP4)
Description of the patch: This update for the Linux Kernel 5.14.21-150400_24_18 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 34 for SLE 12 SP5)
Description of the patch: This update for the Linux Kernel 4.12.14-122_130 fixes several issues.
The following security issues were fixed:
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-1390: Fixed remote DoS vulnerability in tipc_link_xmit() (bsc#1210779).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Vulnerability from csaf_suse - Published: 2023-06-29 17:05 - Updated: 2023-06-29 17:05Summary
Security update for the Linux Kernel (Live Patch 23 for SLE 15 SP3)
Severity
Important
Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 23 for SLE 15 SP3)
Description of the patch: This update for the Linux Kernel 5.3.18-150300_59_90 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).

Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 3 for SLE 15 SP4)
Description of the patch: This update for the Linux Kernel 5.14.21-150400_24_21 fixes several issues.
The following security issues were fixed:
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 22 for SLE 15 SP3)
Description of the patch: This update for the Linux Kernel 5.3.18-150300_59_87 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-1390: Fixed remote DoS vulnerability in tipc_link_xmit() (bsc#1210779).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 6 for SLE 15 SP4)
Description of the patch: This update for the Linux Kernel 5.14.21-150400_24_38 fixes several issues.
The following security issues were fixed:
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).

SUSE-SU-2023:2755-1
Vulnerability from csaf_suse - Published: 2023-06-30 13:58 - Updated: 2023-06-30 13:58Summary
Security update for the Linux Kernel (Live Patch 1 for SLE 15 SP4)
Severity
Important
Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 1 for SLE 15 SP4)
Description of the patch: This update for the Linux Kernel 5.14.21-150400_24_11 fixes several issues.
The following security issues were fixed:
- CVE-2022-4744: Fixed double-free that could lead to DoS or privilege escalation in TUN/TAP device driver functionality (bsc#1209672).
- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
- CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
- CVE-2023-28466: Fixed race condition that could lead to use-after-free or NULL pointer dereference in do_tls_getsockopt in net/tls/tls_main.c (bsc#1210452).
