CVE-2021-3489
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an malicious user to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed ...

CVE-2021-3490
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4...

CVE-2009-3001
The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and previous versions does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.

CVE-2009-3002
The Linux kernel prior to 2.6.31-rc7 does not initialize certain data structures within getname functions, which allows local users to read the contents of some kernel memory locations by calling getsockname on (1) an AF_APPLETALK socket, related to the atalk_getname function in ...

CVE-2010-3084
Buffer overflow in the niu_get_ethtool_tcam_all function in drivers/net/niu.c in the Linux kernel prior to 2.6.36-rc4 allows local users to cause a denial of service or possibly have unspecified other impact via the ETHTOOL_GRXCLSRLALL ethtool command.

CVE-2019-15791
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes...

CVE-2019-15792
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() calls fdget(oldfd), then without further checks passes the resulting file* into shiftfs_real_fdget(), which casts file->private_data, a void*...
