https://notcve.org/view.php?id=CVE-2022-41858
A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information. • https://github.com/torvalds/linux/commit/ec4eb8a86ade4d22633e1da2a7d85a846b7d1798 https://security.netapp.com/advisory/ntap-20230223-0006 https://access.redhat.com/security/cve/CVE-2022-41858 https://bugzilla.redhat.com/show_bug.cgi?id=2144379 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •
CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 1CVE-2022-47929 – kernel: NULL pointer dereference in traffic control subsystem
https://notcve.org/view.php?id=CVE-2022-47929
In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c. A NULL pointer dereference flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux kernel. This issue may allow a local unprivileged user to trigger a denial of service if the alloc_workqueue function return is not validated in time of failure, resulting in a system crash or leaked internal kernel information. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=96398560f26aa07e8f2969d73c8197e6a6d10407 https://lists.debian.org/debian-lts-announce/2023/03/msg00000.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://tldp.org/HOWTO/Traffic-Control-HOWTO/components.html https://www.debian.org/security/2023/dsa-5324 https://www.spinics.net/lists/netdev/msg555705.html https:// • CWE-476: NULL Pointer Dereference •

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') •

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.
