https://notcve.org/view.php?id=CVE-2024-23196
A race condition was found in the Linux kernel's sound/hda device driver in snd_hdac_regmap_sync() function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue. Se encontró una condición de ejecución en el controlador de dispositivo de sonido/hda del kernel de Linux en la función snd_hdac_regmap_sync(). Esto puede provocar un problema de desreferencia de puntero nulo, lo que posiblemente provoque un pánico en el kernel o un problema de denegación de servicio. • https://bugzilla.openanolis.cn/show_bug.cgi?id=8148 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-476: NULL Pointer Dereference •

CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 12CVE-2024-1086 – Linux Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2024-1086
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. Una vulnerabilidad de use after free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. La función nft_verdict_init() permite valores positivos como error de eliminación dentro del veredicto del gancho y, por lo tanto, la función nf_hook_slow() puede causar una vulnerabilidad double free cuando NF_DROP se emite con un error de eliminación similar a NF_ACCEPT. Recomendamos actualizar después del compromiso f342de4e2f33e0e39165d8639387aa6c19dff660. A flaw was found in the Netfilter subsystem in the Linux kernel. • https://github.com/Notselwyn/CVE-2024-1086 https://github.com/feely666/CVE-2024-1086 https://github.com/CCIEVoice2009/CVE-2024-1086 https://github.com/pl0xe/CVE-2024-1086 https://github.com/xzx482/CVE-2024-1086 https://github.com/kevcooper/CVE-2024-1086-checker https://github.com/matrixvk/CVE-2024-1086-aarch64 https://github.com/Alicey0719/docker-POC_CVE-2024-1086 https://github.com/LLfam/CVE-2024-1086 http://www.openwall.com/lists/oss-security/2024/04/10/22 h • CWE-416: Use After Free •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 1CVE-2024-0564 – Kernel: max page sharing of kernel samepage merging (ksm) may cause memory deduplication
https://notcve.org/view.php?id=CVE-2024-0564
A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page. • https://access.redhat.com/security/cve/CVE-2024-0564 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680513 https://bugzilla.redhat.com/show_bug.cgi?id=2258514 https://link.springer.com/conference/wisa https://wisa.or.kr/accepted • CWE-203: Observable Discrepancy •
