CVE-2023-23003
https://notcve.org/view.php?id=CVE-2023-23003
01 Mar 2023 — In the Linux kernel before 5.16, tools/perf/util/expr.c lacks a check for the hashmap__new return value. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.16 • CWE-252: Unchecked Return Value •
CVE-2023-23005
https://notcve.org/view.php?id=CVE-2023-23005
01 Mar 2023 — In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 • CWE-476: NULL Pointer Dereference •

01 Mar 2023 — In the Linux kernel before 5.15.13, drivers/net/ethernet/mellanox/mlx5/core/steering/dr_domain.c misinterprets the mlx5_get_uars_page 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/v5.x/ChangeLog-5.15.13 • CWE-476: NULL Pointer Dereference •
CVE-2023-23000 – Ubuntu Security Notice USN-6704-4
https://notcve.org/view.php?id=CVE-2023-23000
01 Mar 2023 — In the Linux kernel before 5.17, drivers/phy/tegra/xusb.c mishandles the tegra_xusb_find_port_node return value. Callers expect NULL in the error case, but an error pointer is used. Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service. It was discovered that the DesignWare U... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17 • CWE-476: NULL Pointer Dereference •

01 Mar 2023 — In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer). Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection.

28 Feb 2023 — In the Linux kernel before 5.17.2, drivers/soc/qcom/qcom_aoss.c does not release an of_find_device_by_node reference after use, e.g., with put_device. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.2 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2023-22998 – kernel: drm/virtio: improper return value check in virtio_gpu_object_shmem_init()
https://notcve.org/view.php?id=CVE-2023-22998
28 Feb 2023 — 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 • CWE-436: Interpretation Conflict •

28 Feb 2023 — In the Linux kernel before 5.16.3, drivers/usb/dwc3/dwc3-qcom.c misinterprets the dwc3_qcom_create_urs_usb_platdev 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/v5.x/ChangeLog-5.16.3 • CWE-476: NULL Pointer Dereference •
CVE-2023-1095 – kernel: netfilter: NULL pointer dereference in nf_tables due to zeroed list head
https://notcve.org/view.php?id=CVE-2023-1095
28 Feb 2023 — 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 allow... • https://bugzilla.redhat.com/show_bug.cgi?id=2173973 • CWE-476: NULL Pointer Dereference •
CVE-2023-22995 – Ubuntu Security Notice USN-6681-2

28 Feb 2023 — In the Linux kernel before 5.17, an error path in dwc3_qcom_acpi_register_core in drivers/usb/dwc3/dwc3-qcom.c lacks certain platform_device_put and kfree calls. Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection.
