CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-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') •

There exists a use-after-free vulnerability in the Linux kernel through io_uring and the IORING_OP_SPLICE operation. If IORING_OP_SPLICE is missing the IO_WQ_WORK_FILES flag, which signals that the operation won't use current->nsproxy, so its reference counter is not increased. This assumption is not always true as calling io_splice on specific files will call the get_uts function which will use current->nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability. We recommend upgrading to version 5.10.160 or above Existe una vulnerabilidad de use-after-free en el kernel de Linux a través de io_uring y la operación IORING_OP_SPLICE. Si a IORING_OP_SPLICE le falta el indicador IO_WQ_WORK_FILES, que indica que la operación no utilizará current->nsproxy, por lo que su contador de referencia no aumenta. • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=75454b4bbfc7e6a4dd8338556f36ea9107ddf61a https://kernel.dance/#75454b4bbfc7e6a4dd8338556f36ea9107ddf61a • CWE-416: Use After Free CWE-763: Release of Invalid Pointer or Reference •

A use-after-free flaw was found in the Linux kernel MCTP (Management Component Transport Protocol) functionality. This issue occurs when a user simultaneously calls DROPTAG ioctl and socket close happens, which could allow a local user to crash the system or potentially escalate their privileges on the system. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3a732b46736cd8a29092e4b0b1a9ba83e672bf89 https://security.netapp.com/advisory/ntap-20230223-0005 • CWE-416: Use After Free •
