| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-05-24 | CVE-2021-47516 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfp: Fix memory leak in nfp_cpp_area_cache_add() In line 800 (#1), nfp_cpp_area_alloc() allocates and initializes a CPP area structure. | 5.5 |
| 2024-05-24 | CVE-2021-47517 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ethtool: do not perform operations on net devices being unregistered There is a short period between a net device starts to be unregistered and when it is actually gone. | 7.8 |
| 2024-05-24 | CVE-2021-47518 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfc: fix potential NULL pointer deref in nfc_genl_dump_ses_done The done() netlink callback nfc_genl_dump_ses_done() should check if received argument is non-NULL, because its allocation could fail earlier in dumpit() (nfc_genl_dump_ses()). | 5.5 |
| 2024-05-24 | CVE-2021-47519 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: m_can: m_can_read_fifo: fix memory leak in error branch In m_can_read_fifo(), if the second call to m_can_fifo_read() fails, the function jump to the out_fail label and returns without calling m_can_receive_skb(). | 5.5 |
| 2024-05-24 | CVE-2021-47520 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: pch_can: pch_can_rx_normal: fix use after free After calling netif_receive_skb(skb), dereferencing skb is unsafe. Especially, the can_frame cf which aliases skb memory is dereferenced just after the call netif_receive_skb(skb). Reordering the lines solves the issue. | 7.8 |
| 2024-05-24 | CVE-2021-47521 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: sja1000: fix use after free in ems_pcmcia_add_card() If the last channel is not available then "dev" is freed. | 7.8 |
| 2024-05-24 | CVE-2021-47522 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: bigbenff: prevent null pointer dereference When emulating the device through uhid, there is a chance we don't have output reports and so report_field is null. | 5.5 |
| 2024-05-24 | CVE-2021-47525 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: serial: liteuart: fix use-after-free and memleak on unbind Deregister the port when unbinding the driver to prevent it from being used after releasing the driver data and leaking memory allocated by serial core. | 7.8 |
| 2024-05-24 | CVE-2021-47526 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: serial: liteuart: Fix NULL pointer dereference in ->remove() drvdata has to be set in _probe() - otherwise platform_get_drvdata() causes null pointer dereference BUG in _remove(). | 5.5 |
| 2024-05-24 | CVE-2021-47528 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: Fix a NULL pointer dereference in cdnsp_endpoint_init() In cdnsp_endpoint_init(), cdnsp_ring_alloc() is assigned to pep->ring and there is a dereference of it in cdnsp_endpoint_init(), which could lead to a NULL pointer dereference on failure of cdnsp_ring_alloc(). Fix this bug by adding a check of pep->ring. This bug was found by a static analyzer. | 5.5 |
