| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2022-49603 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ip: Fix data-races around sysctl_ip_fwd_update_priority. While reading sysctl_ip_fwd_update_priority, it can be changed concurrently. | 4.7 |
| 2025-02-26 | CVE-2022-49604 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ip: Fix data-races around sysctl_ip_fwd_use_pmtu. While reading sysctl_ip_fwd_use_pmtu, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers. | 4.7 |
| 2025-02-26 | CVE-2022-49607 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: perf/core: Fix data race between perf_event_set_output() and perf_mmap_close() Yang Jihing reported a race between perf_event_set_output() and perf_mmap_close(): CPU1 CPU2 perf_mmap_close(e2) if (atomic_dec_and_test(&e2->rb->mmap_count)) // 1 - > 0 detach_rest = true ioctl(e1, IOC_SET_OUTPUT, e2) perf_event_set_output(e1, e2) ... list_for_each_entry_rcu(e, &e2->rb->event_list, rb_entry) ring_buffer_attach(e, NULL); // e1 isn't yet added and // therefore not detached ring_buffer_attach(e1, e2->rb) list_add_rcu(&e1->rb_entry, &e2->rb->event_list) After this; e1 is attached to an unmapped rb and a subsequent perf_mmap() will loop forever more: again: mutex_lock(&e->mmap_mutex); if (event->rb) { ... if (!atomic_inc_not_zero(&e->rb->mmap_count)) { ... mutex_unlock(&e->mmap_mutex); goto again; } } The loop in perf_mmap_close() holds e2->mmap_mutex, while the attach in perf_event_set_output() holds e1->mmap_mutex. | 4.7 |
| 2025-02-26 | CVE-2022-49608 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for null return of devm_kcalloc Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.". | 5.5 |
| 2025-02-26 | CVE-2022-49609 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe of_find_matching_node_and_match() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. | 5.5 |
| 2025-02-26 | CVE-2022-49615 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error The initial settings will be written before the codec probe function. But, the rt711->component doesn't be assigned yet. If IO error happened during initial settings operations, it will cause the kernel panic. This patch changed component->dev to slave->dev to fix this issue. | 5.5 |
| 2025-02-26 | CVE-2022-49618 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux() pdesc could be null but still dereference pdesc->name and it will lead to a null pointer access. | 5.5 |
| 2025-02-26 | CVE-2022-49619 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: sfp: fix memory leak in sfp_probe() sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). | 5.5 |
| 2025-02-26 | CVE-2022-49620 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: tipc: fix possible refcount leak in tipc_sk_create() Free sk in case tipc_sk_insert() fails. | 5.5 |
| 2025-02-26 | CVE-2022-49621 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cpufreq: pmac32-cpufreq: Fix refcount leak bug In pmac_cpufreq_init_MacRISC3(), we need to add corresponding of_node_put() for the three node pointers whose refcount have been incremented by of_find_node_by_name(). | 5.5 |
