A flaw was found in hw. Processor optimization removal or modification of security-critical code for some Intel processors may potentially allow an authenticated user to enable information disclosure via local access

There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions ...

A use-after-free flaw was found in u32_change in net/sched/cls_u32.c in the network subcomponent of the Linux kernel. This flaw allows a local attacker to crash the system, cause a privilege escalation, and leak kernel information.

An out-of-bounds write flaw was found in the Linux kernel's framebuffer-based console driver functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a local user to crash or potentially escalate their privileges on the system. A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel lockdown was enabled A ...

An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. A bug in the IMA subsystem was discovered which wo ...

A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or ...
