|---|---|---|---|
| 2024-05-24 | CVE-2021-47557 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_ets: don't peek at classes beyond 'nbands' when the number of DRR classes decreases, the round-robin active list can contain elements that have already been freed in ets_qdisc_change(). | 5.5 |
| 2024-05-24 | CVE-2021-47559 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/smc: Fix NULL pointer dereferencing in smc_vlan_by_tcpsk() Coverity reports a possible NULL dereferencing problem: in smc_vlan_by_tcpsk(): 6. | 5.5 |
| 2024-05-24 | CVE-2021-47560 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum: Protect driver from buggy firmware When processing port up/down events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not the CPU port (local port 0), which exists, but lacks a netdev. This can result in a NULL pointer dereference when calling netif_carrier_{on,off}(). Fix this by bailing early when processing an event reported for the CPU port. | 5.5 |
| 2024-05-24 | CVE-2021-47562 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: fix vsi->txq_map sizing The approach of having XDP queue per CPU regardless of user's setting exposed a hidden bug that could occur in case when Rx queue count differ from Tx queue count. | 5.5 |
| 2024-05-24 | CVE-2021-47568 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix memleak in get_file_stream_info() Fix memleak in get_file_stream_info() | 5.5 |
| 2024-05-24 | CVE-2021-47570 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: staging: r8188eu: fix a memory leak in rtw_wx_read32() Free "ptmp" before returning -EINVAL. | 5.5 |
| 2024-05-24 | CVE-2021-47572 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: nexthop: fix null pointer dereference when IPv6 is not enabled When we try to add an IPv6 nexthop and IPv6 is not enabled (!CONFIG_IPV6) we'll hit a NULL pointer dereference[1] in the error path of nh_create_ipv6() due to calling ipv6_stub->fib6_nh_release. | 5.5 |
| 2024-05-23 | CVE-2024-36011 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Fix potential null-ptr-deref Fix potential null-ptr-deref in hci_le_big_sync_established_evt(). | 5.5 |
| 2024-05-22 | CVE-2021-47490 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/ttm: fix memleak in ttm_transfered_destroy We need to cleanup the fences for ghost objects as well. Bug: https://bugzilla.kernel.org/show_bug.cgi?id=214029 Bug: https://bugzilla.kernel.org/show_bug.cgi?id=214447 | 5.5 |
| 2024-05-22 | CVE-2021-47435 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dm: fix mempool NULL pointer race when completing IO dm_io_dec_pending() calls end_io_acct() first and will then dec md in-flight pending count. | 4.7 |
