2023-02-02 CVE-2023-25012 Use After Free vulnerability in Linux Kernel
The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a crafted USB device because the LED controllers remain registered for too long.

2023-01-30 CVE-2023-0240 Use After Free vulnerability in Linux Kernel
There is a logic error in io_uring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the last io_grab_identity call cannot return false is not true, and in this case the function will use the init_cred or the previous linked requests identity to do operations instead of using the current identity.

2023-01-30 CVE-2023-0266 Use After Free vulnerability in Linux Kernel
A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user.
