05 May 2023 — An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order for an attacker to exploit this, the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.11 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-2156
04 May 2023 — A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability... • http://www.openwall.com/lists/oss-security/2023/05/17/8 • CWE-617: Reachable Assertion •

28 Apr 2023 — qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. An out-of-bounds memory access flaw was found in the Linux kernel’s traffic control (QoS) subsystem in how a user triggers the qfq_change_class function with an incorrect MTU value of the network device used as lmax. This flaw allows a local user to crash or potentially escalate their privileges on the system. This vulnerability allows local attackers to escalate priv... • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html • CWE-787: Out-of-bounds Write •

26 Apr 2023 — A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents.

https://notcve.org/view.php?id=CVE-2023-1998
20 Apr 2023 — The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened beca... • https://www.exploit-db.com/exploits/51384 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-1303: Non-Transparent Sharing of Microarchitectural Resources •

20 Apr 2023 — An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer.
