| 2024-05-19 | CVE-2024-35902 | NULL Pointer Dereference vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: net/rds: fix possible cp null dereference cp might be null, calling cp->cp_conn would produce null dereference [Simon Horman adds:] Analysis: * cp is a parameter of __rds_rdma_map and is not reassigned. * The following call-sites pass a NULL cp argument to __rds_rdma_map() - rds_get_mr() - rds_get_mr_for_dest * Prior to the code above, the following assumes that cp may be NULL (which is indicative, but could itself be unnecessary) trans_private = rs->rs_transport->get_mr( sg, nents, rs, &mr->r_key, cp ? cp->cp_conn : NULL, args->vec.addr, args->vec.bytes, need_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED); * The code modified by this patch is guarded by IS_ERR(trans_private), where trans_private is assigned as per the previous point in this analysis. The only implementation of get_mr that I could locate is rds_ib_get_mr() which can return an ERR_PTR if the conn (4th) argument is NULL. * ret is set to PTR_ERR(trans_private). rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL. Thus ret may be -ENODEV in which case the code in question will execute. Conclusion: * cp may be NULL at the point where this patch adds a check; this patch does seem to address a possible bug | 5.5 |
| 2024-05-19 | CVE-2024-35904 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: selinux: avoid dereference of garbage after mount failure In case kern_mount() fails and returns an error pointer return in the error branch instead of continuing and dereferencing the error pointer. While on it drop the never read static variable selinuxfs_mount. | 5.5 |
| 2024-05-19 | CVE-2024-35905 | Improper Validation of Array Index vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: bpf: Protect against int overflow for stack access size This patch re-introduces protection against the size of access to stack memory being negative; the access size can appear negative as a result of overflowing its signed int representation. | 7.8 |
| 2024-05-19 | CVE-2024-35907 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxbf_gige: call request_irq() after NAPI initialized The mlxbf_gige driver encounters a NULL pointer exception in mlxbf_gige_open() when kdump is enabled. | 5.5 |
| 2024-05-19 | CVE-2024-35915 | Use of Uninitialized Resource vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet syzbot reported the following uninit-value access issue [1][2]: nci_rx_work() parses and processes received packet. | 5.5 |
| 2024-05-17 | CVE-2023-52675 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: powerpc/imc-pmu: Add a null pointer check in update_events_in_group() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. | 5.5 |
| 2024-05-17 | CVE-2023-52679 | Double Free vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: of: Fix double free in of_parse_phandle_with_args_map In of_parse_phandle_with_args_map() the inner loop that iterates through the map entries calls of_node_put(new) to free the reference acquired by the previous iteration of the inner loop. | 7.8 |
| 2024-05-17 | CVE-2023-52686 | In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv: Add a null pointer check in opal_event_init() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. | 5.5 |
| 2024-05-17 | CVE-2023-52690 | In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv: Add a null pointer check to scom_debug_init_one() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Add a null pointer check, and release 'ent' to avoid memory leaks. | 5.5 |
| 2024-05-17 | CVE-2023-52691 | Double Free vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix a double-free in si_dpm_init When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. | 7.8 |
