https://notcve.org/view.php?id=CVE-2023-2194
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. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.

https://notcve.org/view.php?id=CVE-2023-2177
A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a denial of service. A NULL pointer dereference issue was found in the SCTP network protocol in net/sctp/stream_sched.c in the Linux kernel. If stream_in allocation fails, stream_out is freed, which would be accessed further. • https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=181d8d2066c0 https://access.redhat.com/security/cve/CVE-2023-2177 https://bugzilla.redhat.com/show_bug.cgi?id=2187953 • CWE-476: NULL Pointer Dereference •

A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows a local user to crash or potentially cause a denial of service. • https://bugzilla.redhat.com/show_bug.cgi?id=2177382 https://access.redhat.com/security/cve/CVE-2023-28327 • CWE-476: NULL Pointer Dereference •
