https://notcve.org/view.php?id=CVE-2023-2124
An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/xfs/xfs_buf_item_recover.c?h=v6.4-rc1&id=22ed903eee23a5b174e240f1cdfa9acf393a5210 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security.netapp.com/advisory/ntap-20230622-0010 https://syzkaller.appspot.com/bug?extid=7e9494b8b399902e994e https://www.debian.org/security/2023/dsa-5448 https://www.debian.org/security/2023/dsa-5480 https://access.redhat.com/security/cve/CVE-2023-2124 https&# • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors.

A use-after-free flaw was found in xen_9pfs_front_removet in net/9p/trans_xen.c in Xen transport for 9pfs in the Linux Kernel. This flaw could allow a local attacker to crash the system due to a race problem, possibly leading to a kernel information leak. • https://lore.kernel.org/all/20230313090002.3308025-1-zyytlz.wz%40163.com • CWE-416: Use After Free •

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 https://github.com/torvalds/linux/commit/611792920925fb088ddccbe2783c7f92fdfb6b64 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-0458
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.
