In the Linux kernel before 5124, net/bluetooth/hci_eventc has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409 This leads to writing an arbitrary value ...

A use-after-free flaw was found in hci_send_acl in the bluetooth host controller interface (HCI) in Linux kernel, where a local attacker with an access rights could cause a denial of service problem on the system The issue results from the object hchan, freed in hci_disconn_loglink_complete_evt, yet still used in other places The highest threat f ...

A flaw was found in the Linux kernels implementation of wifi fragmentation handling An attacker with the ability to transmit within the wireless transmission range of an access point can abuse a flaw where previous contents of wifi fragments can be unintentionally transmitted to another device (CVE-2020-24586) A flaw was found in the Linux kernel ...
