This would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space.\n\nFor the Red Hat Enterprise Linux 7 the eBPF for unprivileged users is always disabled.\nFor the Red Hat Enterprise Linux 8 to confirm the current state, inspect the sysctl with the command:\n\n# cat /proc/sys/kernel/unprivileged_bpf_disabled\n\nThe setting of 1 would mean that unprivileged users can not use eBPF, mitigating the flaw.\n\nA kernel update will be required to mitigate the flaw for the root or users with CAP_SYS_ADMIN capabilities.",

"details": "To mitigate these vulnerabilities on the operating system level, disable the Bluetooth functionality via blocklisting kernel modules in the Linux kernel. The kernel modules can be prevented from being loaded by using system-wide modprobe rules. Instructions on how to disable Bluetooth modules are available on the customer portal at https://access.redhat.com/solutions/2682931.\n\nAlternatively, bluetooth can be disabled within the hardware or at the BIOS level, which will also provide effective mitigation as the kernel will not detect Bluetooth hardware on the system.",

"text": "This vulnerability poses a moderate severity risk due to its potential to trigger a use-after-free issue when processing IGMPv2 query packets under specific conditions. An attacker could exploit this flaw by continuously sending crafted IGMPv2 query packets to a vulnerable system, causing a reference count underflow in the multicast group list management. Subsequently, this could lead to a use-after-free scenario, potentially resulting in a denial-of-service condition or other adverse effects. While exploitation requires specific configurations and continuous packet transmission, the impact could be significant, warranting attention and remediation to prevent potential exploitation and system instability.",

"text": "The vulnerability identified as CVE-2023-24023, dubbed \"Bluetooth Forward and Future Secrecy Attacks and Defenses (BLUFFS),\" is categorized as having moderate severity due to several factors. While it does allow for potential Man-in-The-Middle (MITM) attacks between paired Bluetooth BR/EDR devices, its impact is somewhat limited by certain conditions. Firstly, successful exploitation requires the attacker to be within wireless range of the vulnerable devices during the encryption procedure initiation. Additionally, the attacker\u0027s ability to force a reduction in encryption key length may not guarantee real-time brute-forcing of the key, particularly if it exceeds 7 octets.",

The new value is tested for validity by\ntemporarily loading it into the fpc register.\n\nThis may lead to corruption of the fpc register of the host process:\nif an interrupt happens while the value is temporarily loaded into the fpc\nregister, and within interrupt context floating point or vector registers\nare used, the current fp/vx registers are saved with save_fpu_regs()\nassuming they belong to user space and will be loaded into fp/vx registers\nwhen returning to user space.\n\ntest_fp_ctl() restores the original user space / host process fpc register\nvalue, however it will be discarded, when returning to user space.\n\nIn result the host process will incorrectly continue to run with the value\nthat was supposed to be used for a guest cpu.\n\nFix this by simply removing the test. There is another test right before\nthe SIE context is entered which will handles invalid values.\n\nThis results in a change of behaviour: invalid values will now be accepted\ninstead of that the ioctl fails with -EINVAL. This seems to be acceptable,\ngiven that this interface is most likely not used anymore, and this is in\naddition the same behaviour implemented with the memory mapped interface\n(replace invalid values with zero) - see sync_regs() in kvm-s390.c.",
