CVE-2023-23455 – Kernel: denial of service in atm_tc_enqueue in net/sched/sch_atm.c due to type confusion
https://notcve.org/view.php?id=CVE-2023-23455
atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results). A denial of service flaw was found in atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel. This issue may allow a local attacker to cause a denial of service due to type confusion. Non-negative numbers could indicate a TC_ACT_SHOT condition rather than valid classification results. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a2965c7be0522eaa18808684b7b82b248515511b https://lists.debian.org/debian-lts-announce/2023/03/msg00000.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://www.debian.org/security/2023/dsa-5324 https://www.openwall.com/lists/oss-security/2023/01/10/1 https://www.openwall.com/lists/oss-security/2023/01/10/4 https://access.redhat.com/security/cve/CVE-2023-23455 https:/ • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVE-2023-23454 – kernel: slab-out-of-bounds read vulnerabilities in cbq_classify
https://notcve.org/view.php?id=CVE-2023-23454
cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results). An out-of-bounds (OOB) read problem was found in cbq_classify in net/sched/sch_cbq.c in the Linux kernel. This issue may allow a local attacker to cause a denial of service due to type confusion. Non-negative numbers could indicate a TC_ACT_SHOT condition rather than valid classification results. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=caa4b35b4317d5147b3ab0fbdc9c075c7d2e9c12 https://lists.debian.org/debian-lts-announce/2023/03/msg00000.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://www.debian.org/security/2023/dsa-5324 https://www.openwall.com/lists/oss-security/2023/01/10/1 https://www.openwall.com/lists/oss-security/2023/01/10/4 https://access.redhat.com/security/cve/CVE-2023-23454 https:/ • CWE-125: Out-of-bounds Read CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
