CVE-2024-42320 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix error checks in dasd_copy_pair_store() dasd_add_busid() can return an error via ERR_PTR() if an allocation fails. However, two callsites in dasd_copy_pair_store() do not check the result, potentially resulting in a NULL pointer dereference. Fix this by checking the result with IS_ERR() and returning the error up the stack.
CVE-2024-42310 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/gma500: fix null pointer dereference in cdv_intel_lvds_get_modes In cdv_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.
CVE-2024-42309 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/gma500: fix null pointer dereference in psb_intel_lvds_get_modes In psb_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.
CVE-2024-42308 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check for NULL pointer [why & how] Need to make sure plane_state is initialized before accessing its members. (cherry picked from commit 295d91cbc700651782a60572f83c24861607b648)
CVE-2024-42307 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: cifs: fix potential null pointer use in destroy_workqueue in init_cifs error path Dan Carpenter reported a Smack static checker warning: fs/smb/client/cifsfs.c:1981 init_cifs() error: we previously assumed 'serverclose_wq' could be null (see line 1895) The patch which introduced the serverclose workqueue used the wrong oredering in error paths in init_cifs() for freeing it on errors.

CVE-2024-42282 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: mediatek: Fix potential NULL pointer dereference in dummy net_device handling Move the freeing of the dummy net_device from mtk_free_dev() to mtk_remove(). Previously, if alloc_netdev_dummy() failed in mtk_probe(), eth->dummy_dev would be NULL. The error path would then call mtk_free_dev(), which in turn called free_netdev() assuming dummy_dev was allocated (but it was not), potentially causing a NULL pointer dereference. By moving free_netdev() to mtk_remove(), we ensure it's only called when mtk_probe() has succeeded and dummy_dev is fully allocated. This addresses a potential NULL pointer dereference detected by Smatch[1].
CVE-2024-42278 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: TAS2781: Fix tasdev_load_calibrated_data() This function has a reversed if statement so it's either a no-op or it leads to a NULL dereference.
CVE-2024-42277 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iommu: sprd: Avoid NULL deref in sprd_iommu_hw_en In sprd_iommu_cleanup() before calling function sprd_iommu_hw_en() dom->sdev is equal to NULL, which leads to null dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE.
CVE-2024-42276 2024-09-15 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: add missing condition check for existence of mapped data nvme_map_data() is called when request has physical segments, hence the nvme_unmap_data() should have same condition to avoid dereference.
CVE-2024-42270 1 Linux 1 Linux Kernel 2024-09-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fix null-ptr-deref in iptable_nat_table_init(). We had a report that iptables-restore sometimes triggered null-ptr-deref at boot time. [0] The problem is that iptable_nat_table_init() is exposed to user space before the kernel fully initialises netns. In the small race window, a user could call iptable_nat_table_init() that accesses net_generic(net, iptable_nat_net_id), which is available only after registering iptable_nat_net_ops. Let's call register_pernet_subsys() before xt_register_template().

CVE-2024-2496 1 Redhat 2 Advanced Virtualization, Enterprise Linux 2024-09-14 5 Medium
A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by causing the libvirt daemon to crash.

A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel hugetlbfs (HugeTLB pages) functionality. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-6915 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-09-14 6.2 Medium
A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return.
