2024-08-22 CVE-2022-48940 In the Linux kernel, the following vulnerability has been resolved: bpf: Fix crash due to incorrect copy_map_value When both bpf_spin_lock and bpf_timer are present in a BPF map value, copy_map_value needs to skirt both objects when copying a value into and out of the map. However, the current code does not set both s_off and t_off in copy_map_value, which leads to a crash when e.g. bpf_spin_lock is placed in map value with bpf_timer, as bpf_map_update_elem call will be able to overwrite...

2024-08-22 CVE-2022-48941 In the Linux kernel, the following vulnerability has been resolved: ice: fix concurrent reset and removal of VFs Commit c503e63200c6 ("ice: Stop processing VF messages during teardown") introduced a driver state flag, ICE_VF_DEINIT_IN_PROGRESS, which is intended to prevent some issues with concurrently handling messages from VFs while tearing down the VFs. This change was motivated by crashes caused while tearing down and bringing up VFs in rapid succession. It turns out that the fix... Linux_kernel 4.7
2024-08-22 CVE-2022-48942 In the Linux kernel, the following vulnerability has been resolved: hwmon: Handle failure to register sensor with thermal zone correctly If an attempt is made to a sensor with a thermal zone and it fails, the call to devm_thermal_zone_of_sensor_register() may return -ENODEV. This may result in crashes similar to the following. Unable to handle kernel NULL pointer dereference at virtual address 00000000000003cd ... Internal error: Oops: 96000021 [#1] PREEMPT SMP ... pstate: 60400009 (nZCv... Linux_kernel 5.5
2024-08-22 CVE-2022-48943 In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: make apf token non-zero to fix bug In current async pagefault logic, when a page is ready, KVM relies on kvm_arch_can_dequeue_async_page_present() to determine whether to deliver a READY event to the Guest. This function test token value of struct kvm_vcpu_pv_apf_data, which must be reset to zero by Guest kernel when a READY event is finished by Guest. If value is zero meaning that a READY event is done, so... Linux_kernel 7.8
2024-07-30 CVE-2024-42108 In the Linux kernel, the following vulnerability has been resolved: net: rswitch: Avoid use-after-free in rswitch_poll() The use-after-free is actually in rswitch_tx_free(), which is inlined in rswitch_poll(). Since `skb` and `gq->skbs[gq->dirty]` are in fact the same pointer, the skb is first freed using dev_kfree_skb_any(), then the value in skb->len is used to update the interface statistics. Let's move around the instructions to use skb->len before the skb is freed. This bug is... Linux_kernel 7.8
2022-12-23 CVE-2022-47940 An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.18 before 5.18.18. fs/ksmbd/smb2pdu.c lacks length validation in the non-padding case in smb2_write. Linux_kernel 8.1
2023-07-10 CVE-2023-32250 A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel. Linux_kernel, H300s, H410s, H500s, H700s, Hci, Hci_storage_nodes 8.1
2023-07-10 CVE-2023-32254 A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel. Linux_kernel, H300s, H410s, H500s, H700s, Hci_management_node 8.1
2023-10-04 CVE-2023-39191 An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel. Fedora, Linux_kernel, Enterprise_linux 8.2
2023-11-03 CVE-2023-1194 An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory.
