CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-1095 – kernel: netfilter: NULL pointer dereference in nf_tables due to zeroed list head
https://notcve.org/view.php?id=CVE-2023-1095
In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference. A NULL pointer dereference flaw was found in the Linux kernel’s netfilter subsystem. The issue could occur due to an error in nf_tables_updtable while freeing a transaction object not placed on the list head. This flaw allows a local, unprivileged user to crash the system, resulting in a denial of service. • https://bugzilla.redhat.com/show_bug.cgi?id=2173973 https://github.com/torvalds/linux/commit/580077855a40741cf511766129702d97ff02f4d9 https://access.redhat.com/security/cve/CVE-2023-1095 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2023-22998
In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer). • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.0.3 https://github.com/torvalds/linux/commit/c24968734abfed81c8f93dc5f44a7b7a9aecadfa https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://access.redhat.com/security/cve/CVE-2023-22998 https://bugzilla.redhat.com/show_bug.cgi?id=2182429 • CWE-436: Interpretation Conflict •
