DATE CVE VULNERABILITY TITLE RISK
2021-08-02 CVE-2021-34556 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.

2021-08-02 CVE-2021-35477 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.

2021-07-21 CVE-2021-37159 Use After Free vulnerability in multiple products
hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.

2021-03-22 CVE-2021-28972 Classic Buffer Overflow vulnerability in multiple products
In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly.
