UBUNTU-CVE-2023-0045

The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ibprctlset function updates the Thread Information Flags TIFs for the task and updates the SPECCTRL MSR on the function speculationctrlupdate, but the IBPB is only issued on the next...

CVE-2023-0266

A use-after-free flaw was found in sndctlelemread in sound/core/control.c in Advanced Linux Sound Architecture ALSA subsystem in the Linux kernel. In this flaw a normal privileged, local attacker may impact the system due to a locking issue in the compat path, leading to a kernel information leak...
